New: negative search
--------------------

Meilisearch 1.8 allows you to exclude specific terms from your search results using the `-` operator. 

For example, to find documents that contain the word "room" but not "escape", place a `-` before "escape”:

```Bash
curl \
  -X POST 'https://edge.meilisearch.com/indexes/places/search' \
  -H 'Content-Type: application/json' \
  --data-binary '{ "q": "-escape room" }'

```

### New Ollama embedder

Meilisearch 1.8 introduces support for Ollama models. [Configure the embedder](https://meilisearch.org.cn/docs/learn/experimental/vector_search#release-v1-8&utm_source=blog#generate-vector-embeddings) in your index settings:

```JSON
"default": {
  "source": "ollama", // 👈 Use the ollama source
  "url": "http://localhost:11434/api/embeddings",
  // ☝️ optional, fetched from MEILI_OLLAMA_URL environment variable if missing
  "apiKey": "<your-api-key>",
  // ☝️ optional
  "model": "nomic-embed-text",
  "documentTemplate": "{{doc.field_name}}" // like for openAI and huggingFace sources
}

```

### New REST Embedder

Starting with Meilisearch 1.8, you can use any embedder accessible via a REST API. Here’s how to configure an OpenAI embedder with the `rest` source:

```JSON
{
  "source": "rest",
  "apiKey": "<your-openai-api-key>",
  "dimensions": 1536,
  "url": "https://api.openai.com/v1/embeddings",
  "query": {
    "model": "text-embedding-ada-002"
  },
  "inputField": ["input"],
  "inputType": "textArray",
  "pathToEmbeddings": ["data"],
  "embeddingObject": ["embedding"]
}

```

For more details on the API and available parameters, please consult the documentation on [REST embedders](https://meilisearch.org.cn/docs/learn/experimental/vector_search#generate-auto-embeddings#release-v1-8&utm_source=blog).

### New embedder setting: distribution shift

<Callout>
  This is an advanced API for custom models. OpenAI and Hugging Face models don't require this setting.
</Callout>

Depending on the embedding model, [vector embeddings](/blog/what-are-vector-embeddings/#release-v1-8&utm_source=blog) are not always uniformly distributed within the [vector space](/blog/what-are-vector-embeddings/#release-v1-8&utm_source=blog) When vectors are overly clustered, semantic search scores can be very closely ranked. As a result of semantic scores being packed, hybrid results might have sub-optimal relevancy.

To address this issue, you can now shift the distribution of results with an affine transformation. This transformation normalizes semantic scores to prevent them from clustering too high or too tightly, making them more comparable to the [keyword scores](https://meilisearch.org.cn/docs/reference/api/search#ranking-score).

```JSON
"default": {
  "source": "huggingFace",
  "model": "MODEL_NAME",
  "distribution": {  // describes the natural distribution of results
    "mean": 0.7, // mean value
    "sigma": 0.3 // standard deviation
  }
}

```

*   The **mean** value represents the central point around which you observe semantic search scores to be densely packed. In the provided code sample, the setting indicates that semantic scores from this model tend to cluster around a mean of 0.7.
*   The **sigma** value determines the spread of ranking scores from the mean (standard deviation). The sigma provided in the code sample above means that before shifting the distribution, the results tend to have an average distance of 0.3 to the mean.

This allows for a more effective comparison of `_rankingScore` between semantic and keyword search results, leading to improved results ranking.

### Breaking: trimmed API response

To speed up the search response and reduce bandwidth usage, Meilisearch v1.8 no longer returns the following fields in the search responses:

*   the `vector` field, which returned the query vector 
*   the `value` field included in the [`vectorSort`](https://meilisearch.org.cn/docs/reference/api/search#release-v1-8&utm_source=blog#vectorsorttarget_vector) object, which is returned when you add \`”showRankingScoreDetails”: true”\` to a search query
*   the `_semanticScore` field; its value is the same as `_rankingScore`, which you should use instead. Set [`”showRankingScore”: true”`](https://meilisearch.org.cn/docs/reference/api/search#blog&utm_campaign=release-v1-8#ranking-score) in the search parameters

Search robustness improvements
------------------------------

### New search cut-off setting

To enhance stability and performance, Meilisearch automatically terminates any search request that exceeds 1500 milliseconds. 

To adjust this timeout threshold, you can customize the `searchCutoffMs` setting:

```bash
curl \
  -X PATCH 'https://edge.meilisearch.com/indexes/movies/settings' \
  -H 'Content-Type: application/json' \
  --data-binary '{
    "searchCutoffMs": 150
  }'

```

### Experimental: concurrent search requests limit

This release introduces a limit on concurrent search requests to prevent Meilisearch from using excessive amounts of RAM and crashing. The default queue limit is set to 1000 requests. 

To modify this limit, restart your self-hosted instance with the `--experimental-search-queue-size` option:

```bash
./meilisearch --experimental-search-queue-size 100
```

👉 This limit does not impact the search performance. It only controls the number of search requests that can be queued simultaneously to enhance system security.

Improved hybrid & vector search
-------------------------------

<Callout>
  AI search is an experimental feature, read the docs to [enable AI search](https://meilisearch.org.cn/docs/learn/experimental/vector_search#release-v1-7&utm_source=blog#activate-vector-search).
</Callout>

### New OpenAI embedding models

Starting with Meilisearch 1.7, you can use OpenAI’s third-generation embedding models:

*   `text-embedding-3-small`
*   `text-embedding-3-large`

Compared to the previous `text-embedding-ada-002` model, these new models offer improvements allowing to balance search results relevancy and cost efficiency.

The `small` model is more cost-effective, generating smaller vector embeddings that require less storage. The `large` focuses on delivering higher precision in search results, making it ideal to optimize relevancy.

### Configuring OpenAI model dimensions

When using the new `text-embedding-3-small` and `text-embedding-3-large` OpenAI models, you can now configure **dimensions** for your model. When not provided, the model's defaults dimensions are used.

You can do so when updating your settings:

```json
{
  // other settings...

  "embedders": {
    "small": {
      "source": "openAi",
      "model": "text-embedding-3-large",
      "dimensions": 512 // must be >0, must be <= 3072 for "text-embedding-3-large"
    },
  }
}

```

Higher dimensions typically offer more complex embeddings which can lead to more accurate search results. However, increased dimensions are more costly to compute and require more storage.

<Callout>
  You cannot customize dimensions when using OpenAI `text-embedding-ada-002`.

Display ranking scores details at search
----------------------------------------

Meilisearch 1.7 stabilizes the `showRankingScoreDetails` search parameter that was introduced in [Meilisearch 1.3](/blog/v1-3-release/#release-v1-7&utm_source=blog This parameter adds a `_rankingScoreDetails` field to each document in search results, enabling further inspection of the search results.

You can include the parameter when making searches:

```sh
curl \
  -X POST 'https://edge.meilisearch.com/indexes/movies/search' \
  -H 'Content-Type: application/json' \
  --data-binary '{
    "q": "batman",
    "showRankingScoreDetails": true
  }'

```

AI's influence on search
------------------------

The rapid advancement of AI technology is undeniably reshaping human-machine interactions. Historically, communication with machines necessitated intermediaries like programming languages and structured scripts.

Now, with the arrival of GPTs and AI-assisted bots, machine-learning models are approaching a deeper comprehension of natural human language. This evolution brings humans and machines closer, changing the way we seek and find information.

From keyword-based searches to discovery-driven inquiries, people’s approach to search evolves: we are moving from searching for known items to exploring unknown territories, searching and finding the concepts instead of focusing solely on words.

Take a streaming media company: the searches across their platform might include the inquiry for a specific movie title, such as "Back to the Future," as well as conceptually-driven searches like "Give me recommendations for a feel-good sci-fi movie from the 80s".

Consider everyday scenarios: spotting an item on the street and using an image to search for it, or conducting voice searches instead of typing in words on keyboards. These are manifestations of our changing search behaviors.

The pinnacle: hybrid search
---------------------------

While traditional search methods excel in keyword-based queries, they falter with complex, nuanced requests. This is where Meilisearch’s new hybrid search approach comes into play, enriching the efficiency and precision of our robust full-text search engine with a depth of semantic understanding, catering to a wide array of use cases driven by customer-generated data.

Integrating models from AI giants like [OpenAI](https://meilisearch.org.cn/docs/learn/experimental/vector_search#generate-auto-embeddings-with-openai) (open-source embedders generation feature is set for the next release cycle), Meilisearch enables users to create and fine-tune vector embeddings, tailoring their search engine to specific business needs. Moreover, evolving AI models learn from user interactions, continuously improving search precision.

What‘s included in the new release package?
-------------------------------------------

The AI-enhanced hybrid search from Meilisearch leverages our existing robust search infrastructure, including advanced sorting, filtering, faceting, and geo-sorting capabilities, among others.

New release features
--------------------

*   **Enhanced search relevancy**: The AI-enhanced layers bring a deeper semantic understanding, significantly improving result quality.
*   **AI embedders autogeneration:** Choose between using a third-party solution like OpenAI or your own locally generated embeddings. An open-source embedders generation feature is set for the next release cycle.

Cloud monitoring metrics have arrived!

We’re announcing the release of Meilisearch 1.6. Let’s dive into some of the most important changes. You can also view the [full changelog](https://github.com/meilisearch/meilisearch/releases/tag/v1.6.0) on GitHub.

<Callout>
  Meilisearch 1.6 is also available on [Meilisearch Cloud](https://cloud.meilisearch.com/login#release-v1-6&utm_source=blog), including all experimental features.
</Callout>

Experimental feature: hybrid search
-----------------------------------

Meilisearch introduces hybrid search. It combines full-text and semantic search to enhance the accuracy and comprehensiveness of search results. Picture a movie app like [where2watch](https://where2watch.meilisearch.com/#release-v1-6&utm_source=blog). Now, your users will be able to find those movies they can't quite name but remember the story.

Furthermore, Meilisearch now streamlines the creation of vector embeddings. Choose your preferred embedders and Meilisearch will handle all interactions with external tools for you.

### Configuring embedders

You can [configure the embedders](https://meilisearch.org.cn/docs/learn/experimental/vector_search#release-v1-6&utm_source=blog#generate-vector-embeddings) in your index settings. Select from three types of embedders for your needs:

`openAI`:

*   Uses the [OpenAI](https://openai.com/) API for computing embeddings
*   Requires an OpenAI API key for operation

`huggingFace`:

*   Enables local computation of embeddings by downloading models from the [HuggingFace Hub](https://hugging-face.cn/models)
*   Operates on your CPU–not your GPU–which may impact indexing performance

`userProvided`:

*   Functions similarly to Meilisearch v1.3, with a key difference: you must define a specific embedder
*   Allows you to add pre-computed embeddings into your documents. You perform searches using vectors instead of text.

To use hybrid search, define at least one embedder in the index settings:

```JSON
{
  "embedders": {
    "default": {
      "source":  "openAi",
      "apiKey": "<your-OpenAI-API-key>",
      "model": "text-embedding-ada-002",
      "documentTemplate": "A movie titled '{{doc.title}}' whose description starts with {{doc.overview|truncatewords: 20}}"
    },
    "image": {
      "source": "userProvided",
      "dimensions": 512
    },
    "translation": {
      "source": "huggingFace",
      "model": "sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2",
      "documentTemplate": "A movie titled '{{doc.title}}' whose description starts with {{doc.overview|truncatewords: 20}}"
    }
  }
}

```

The `documentTemplate` field acts as a blueprint for creating your document's embedding. It uses the [Liquid template language](https://shopify.dev/docs/api/liquid). While its inclusion is optional, it is highly recommended, especially since embedding models are optimized for concise texts. It keeps only the necessary content, excluding non-essential data like `id`, and helps in adding context to increase relevancy.

### **Hybrid search**

To [perform a hybrid search](https://meilisearch.org.cn/docs/learn/experimental/vector_search#release-v1-6&utm_source=blog#vector-search-with-auto-embeddings), use the hybrid field within the `POST /index/:index_uid/search` route.

```JSON
{
    "q": "Plumbers and dinosaurs",
    "hybrid": {
        "semanticRatio": 0.9,
        "embedder": "default"
    }
}

```

`embedder`: an embedder from the options configured in your index settings.

`semanticRatio`: a floating value ranging from `0` to `1`; `1` is a  fully semantic search; `0` is an exact, match-focused full-text search; the default is `0.5` which mixes both methods.

Your control over the semantic ratio directly influences how search results are ranked. A higher semantic ratio shifts the focus towards the context and meaning behind your query, ranking results that are more semantically relevant higher. 

On the other hand, a lower semantic ratio increases the weight given to keyword accuracy in the ranking process, bringing results that closely match your specific search terms to the forefront.

### **Breaking changes in the experimental vector search API**

Meilisearch v1.6 introduces some breaking changes in the vector search API.

Previously, you could send vectors without specifying a model. Now, you must define a model in the settings:

```JSON
"embedders": {
    "default": {
      "source": "userProvided",
      "dimensions": 512
    }
}

```

Because Meilisearch now supports multiple embedders, it has updated the vector submission format from arrays to JSON objects.

*   Previews format: `“_vectors”: [[0.0, 0.1]]`
*   New format: `“_vectors”: {“image2text”: [0.0, 0.1, …]}`

For detailed information on these updates, refer to the [documentation](https://meilisearch.org.cn/docs/learn/experimental/vector_search#release-v1-6&utm_source=blog).

For in-depth technical information, explore the [series of articles](/blog/spotify-inspired-hybrid-search-and-rust/#release-v1-6&utm_source=blog on [Arroy](https://github.com/meilisearch/arroy), an open-source repository based on [Spotify’s Annoy](https://github.com/spotify/annoy) and developed in Rust. This library, created and maintained by the Meilisearch engine team, specializes in searching for vectors in a space that are near a specified query vector.

**Performance optimization**
----------------------------

### Improved indexing speed

We're thrilled to share a major enhancement in Meilisearch's indexing performance. Our recent tests, including scenarios with frequent and partial document updates, have shown impressive results: **a reduction in indexing time by up to 50%**, and in some cases, **even as much as 75%**. 

Thanks to our latest optimizations, Meilisearch now **stores and pre-computes less data**. Additionally, during document updates, it **re-indexes or deletes only the necessary data**. For instance, in an e-commerce dataset, updating the stock level of a product results in re-indexing just the 'stock' field, rather than the entire product document.

### Disk space usage reduction

Meilisearch reduces internal data storage, leading to a more **compact database size** on your disk. With a dataset of approximately 15Mb, we observed a **40% to 50% reduction in database size**.

This enhancement not only reduces the database size, but also **improves its stability**, making the space savings more evident as the number of documents increases.

**New feature: customize proximity precision**
----------------------------------------------

To further reduce indexing speed, Meilisearch now allows you to tailor the accuracy of the [proximity ranking rule](https://meilisearch.org.cn/docs/learn/core_concepts/relevancy#release-v1-6&utm_source=blog#3-proximity) to your specific needs.

The proximity ranking rule is computationally demanding and may lead to longer indexing times. Reducing its accuracy can greatly enhance performance, and in most scenarios, it will not substantially affect the relevancy of the results.

To adjust its impact [configure the `proximityPrecision` setting](https://meilisearch.org.cn/docs/reference/api/settings#release-v1-6&utm_source=blog#proximity-precision):

```JSON
curl \
  -X PATCH 'http://localhost:7700/indexes/books/settings/proximity-precision' \
  -H 'Content-Type: application/json'  \
  --data-binary '{
    "proximityPrecision": "byAttribute"
  }'
```

The default `proximityPrecision` setting is `byWord`, which calculates proximity based on exact word distances. 

The `byAttribute` setting considers words in the same attribute as proximate, regardless of their exact distance.

Using `byAttribute` can boost the indexing speed, but it might slightly change how relevant the results are. This becomes more noticeable in searches where it's important for words to be close to each other.

For example, when you're looking through song lyrics or long articles, like trying to find 'world war' in a bunch of Wikipedia pages, you might end up with results that contain these words but not necessarily close together or in the desired order. This is also true for [phrase searches](https://meilisearch.org.cn/docs/reference/api/search#release-v1-6&utm_source=blog#phrase-search) and for searches involving [multi-word synonyms](https://meilisearch.org.cn/docs/learn/configuration/synonyms#release-v1-6&utm_source=blog#multi-word-synonyms), where the specific combination of words is crucial.

**New feature: task queue webhook**
-----------------------------------

Meilisearch now offers a webhook feature to notify a custom URL when an asynchronous task finishes (either succeeds, fails, or gets canceled).

This feature is particularly useful for streamlining workflows, saving you from polling the tasks route.

Set up your webhook at launch using these environment variables:

MEILI_TASK_WEBHOOK_URL=https://mywebsite.com/my-super-webhook?user=1234&number=8

MEILI_TASK_WEBHOOK_AUTHORIZATION_HEADER='Bearer 12340987546wowowlolol'
```

You can also use the respective command-line options.

Once set up, the webhook sends out a payload in [JSON Lines (ndjson) format](https://meilisearch.org.cn/docs/learn/core_concepts/documents#release-v1-6&utm_source=blog#ndjson) to your specified URL, containing the list of finished tasks:

```

**Experimental feature: limit the number of batched tasks**
-----------------------------------------------------------

To speed up the indexing process, Meilisearch processes similar [tasks](https://meilisearch.org.cn/docs/learn/async/asynchronous_operations#release-v1-6&utm_source=blog#tasks-and-asynchronous-operations) in large batches. However, excessive [queued tasks](https://meilisearch.org.cn/docs/learn/async/asynchronous_operations#release-v1-6&utm_source=blog#task-queue) can occasionally cause crashes or stalls.

To control the number of batched tasks, set the limit at launch using either the command-line argument `--experimental-max-number-of-batched-tasks`, the `MEILI_EXPERIMENTAL_MAX_NUMBER_OF_BATCHED_TASKS` environment variable, or the [configuration file](https://meilisearch.org.cn/docs/learn/configuration/instance_options#release-v1-6&utm_source=blog#configuration-file).

Meilisearch v1.6

We’re announcing the release of Meilisearch 1.5. Let’s dive into some of the most important changes.

<Callout>
  Meilisearch 1.5 is also available on [Meilisearch Cloud](https://cloud.meilisearch.com/login#release-v1-5&utm_source=blog)—upgrade without any downtime now.
</Callout>

Indexing speed improvements
---------------------------

We’re excited to release the first of a series of improvements to Meilisearch’s indexing speed. 🎉

We’ve noticed **up to 25% faster indexing** depending on the use case. The performance gain is more significant on datasets containing a lot of words like wikis or ebooks.

We’ve achieved this by tweaking the settings for multiple-words queries. If you see any impact on your search relevancy, [let us know](https://github.com/orgs/meilisearch/discussions)!

<Callout>
  Take a look at the [indexing speed benchmarks](https://x.com/StriftCodes/status/1726539789401546880).
</Callout>

There’s more regarding indexing speed in version 1.6—but I don’t want to spoil anything 🤫

New feature: on-demand snapshots
--------------------------------

A [snapshot](https://meilisearch.org.cn/docs/learn/advanced/snapshots#release-v1-5&utm_source=blog) is a copy of your database. Snapshot files are useful to backup your database content and settings. Meilisearch 1.5 introduces the ability to create snapshots on demand.

To create a snapshot, use the [relevant SDK](https://meilisearch.org.cn/docs/learn/what_is_meilisearch/sdks#release-v1-5&utm_source=blog) method or the [REST API](https://meilisearch.org.cn/docs/reference/api/snapshots#release-v1-5&utm_source=blog). In JavaScript, create a snapshot like this:

```javascript
const client = new MeiliSearch({ /* credentials */ })
const task = await client.createSnapshot()
```
<Callout>
  You can also [schedule automatic snapshots](https://meilisearch.org.cn/docs/learn/advanced/snapshots#release-v1-5&utm_source=blog#creating-snapshots) on regular intervals.
</Callout>

Experimental feature: Puffin reports
------------------------------------

Puffin reports allow to get information about what’s happening in the search engine. Enabling this feature will make Meilisearch automatically export .puffin file reports. If you’re encountering performance issues, make sure to share your reports with the Meilisearch team.

This experimental feature can be enabled via the [REST API](https://meilisearch.org.cn/docs/reference/api/experimental_features#release-v1-5&utm_source=blog#configure-experimental-features):

Meilisearch v1.5

You asked for it, and it's finally here! Search analytics has officially landed in the Meilisearch Cloud! We've received numerous [requests](https://roadmap.meilisearch.com/tabs/1-under-consideration) for a way to track key analytics in the Meilisearch Cloud, and we've been hard at work developing a solution that not only empowers you to make data-driven decisions, but also enhances the overall user experience.

So, what's all the buzz about? 🤔
---------------------------------

The new dashboard incorporates a set of metrics providing insights into your users' search behaviors. Its purpose is to give you a quick and comprehensible overview of user search queries and highlight what they might be missing. The implications are vast:

*   Improve recommendations and popular search sections, bolstering e-commerce through cross-selling.
*   Create intelligence reports for your customers.
*   Fine-tune settings and ranking rules to optimize search experiences and inform business decisions.

![](https://unable-actionable-car.media.strapiapp.com/search_analytics_gif_093e60c664.jpg)

What metrics can you expect?
----------------------------

The first iteration of cloud analytics covers the following metrics:

*   Daily searches chart
*   Most searched queries
*   Searches without results
*   Daily search latency
*   Total searches
*   Total users
*   No result rate
*   Click through rate\*
*   Average click position
*   Daily searches per index
*   Conversion\*

\*_The CTR (click-through rate) and the conversion rate_ [_must be configured_](https://meilisearch.org.cn/docs/learn/cloud/analytics#analytics-v1&utm_source=blog) _to fit a specific use case or need._

The default view combines the data from the indexes per project, but it’s also possible to filter out the insights for a specific project of your choice. The dashboard also allows you to select a custom range using a date picker:

![](https://unable-actionable-car.media.strapiapp.com/sa_index_data_picker_gif_56b1687bfd.jpg)

For a detailed walkthrough, check out the [live demo recording of search analytics](https://www.youtube.com/watch?v=yCQWha562M0) on our YouTube channel.

The benefits of search analytics insights
-----------------------------------------

There are numerous advantages to gaining deeper insights into how your users interact with search. With our brand-new dashboard, you can:

*   **Gain rapid, actionable insights into your search performance** at a glance.
*   **Enhance your users' experience** by continuously optimizing result relevancy.
*   **Make more informed business decisions** by understanding your users and their needs.
*   For eCommerce and marketplaces: **develop cross-selling and upselling strategies to boost conversions.**

This marks just the beginning of our optimization and insights journey. Stay tuned for v2, where we will introduce advanced analytics capabilities and subviews.

### Availability and plans

The new Cloud search analytics are available for all Cloud users across all pricing tiers. Each tier has access to the same analytics and chart functionalities of the search analytics dashboard, with the distinction occurring in the _length of data retention_ provided to each tier: 7 days for the Build plan, 30 days for the Grow plan, and 90 days for both Pro and Enterprise plans.

Search analytics have arrived!

Let's take a look at some of the most significant changes in Meilisearch's latest update. We’ll go over the main changes in this article, but you can also view the [full changelog](https://github.com/meilisearch/meilisearch/releases/tag/v1.4.0) on GitHub.

<Callout>
  v1.4 is now available on [Meilisearch Cloud](https://cloud.meilisearch.com/#release-v1-4&utm_source=blog). Upgrade your Meilisearch instance in one click without downtime.
</Callout>

New feature: custom text separators  

--------------------------------------

To make string data searchable, Meilisearch relies on [separators](https://meilisearch.org.cn/docs/learn/advanced/datatypes#release-v1-4&utm_source=blog#separators), as they serve to divide a string into tokens or words. Examples of separators include whitespaces, full-stops, or number signs (#). They play a crucial role in helping Meilisearch segment text effectively and enhance search relevancy.

Meilisearch comes with a predefined list of separators. However, these separators do not suit all use cases. For example, in a hashtag search, the number sign should not be considered a separator, but part of the word.

Starting with v1.4, Meilisearch allows you to customize the separators list to suit your specific needs.

### Using an SDK or the API

<Callout>
  This section shows code samples in JavaScript. Check out our [official SDKs](https://meilisearch.org.cn/docs/learn/what_is_meilisearch/sdks#release-v1-4&utm_source=blog) or the [API reference](https://meilisearch.org.cn/docs/reference/api/settings#release-v1-4&utm_source=blog#separator-tokens) for more examples.
</Callout>

#### Adding characters to the separators list  

To include a character in the separators list, update your index’s _Separators Tokens_ settings:

```JavaScript
client.index('myIndex').updateSeparatorTokens(['&sect;'])
```

This request adds the encoded version of the section sign character (\`§\`) to the separator tokens list.

#### Removing characters from the separators list  

To remove one or more characters from the separators list, update your index’s _Non Separator Tokens_ settings:

```JavaScript
client.index('myIndex').updateNonSeparatorTokens(['@', '#', '&'])
```

### Using Meilisearch Cloud

On [Meilisearch Cloud](https://cloud.meilisearch.com/#release-v1-4&utm_source=blog), you can configure _Separator Tokens_ from your index’s settings. Both fields accept JSON format. To include separators, add them to the 'separators' field. To exclude certain characters as separators, list them under 'non-separators'.

![Screenshot of Meilisearch Cloud UI showcasing the 'separator settings' section. It features two fields: one for listing separators and another for listing non-separators. ](https://unable-actionable-car.media.strapiapp.com/0dfq_LJ_Qj_G_L_Rt9_X_r_F6d6_RKYCTU_Kt_K_ib_Q9_E_Ye3_A8_Cq_V_Ea20_Mv_q3_Pgo_Yrdkbcy_WC_8_QSZN_6f_Bn_D_Wu_QN_87_H_Izf_1_Zyk_FWKKD_Lv_b64487b283.jpg)

New feature: custom dictionary
------------------------------

<Callout>
  This section shows code samples in JavaScript. Check out our [official SDKs](https://meilisearch.org.cn/docs/learn/what_is_meilisearch/sdks#release-v1-4&utm_source=blog) or the [API reference](https://meilisearch.org.cn/docs/reference/api/settings#release-v1-4&utm_source=blog#dictionary) for more examples.
</Callout>

Now, you can add a custom word dictionary to improve Meilisearch's segmentation of specific words. This is particularly useful when working with domain-specific terminology like “Node.js” or proper nouns like “E. E. Cummings”.

To add words to the dictionary, update your index’s _Dictionary_ settings:

```JavaScript
client.index('myIndex').updateDictionary(['e. e.', 'e.e.', 'e e'])
```

On [Meilisearch Cloud](https://cloud.meilisearch.com/#release-v1-4&utm_source=blog), you can configure a _Custom Dictionary_ by providing a JSON array in your index’s settings. You can also upload a JSON file as dictionary.

### Using custom dictionary with stop words and synonyms

The introduction of a custom dictionary acts as a powerful adjunct to existing features like [stopWords](https://meilisearch.org.cn/docs/reference/api/settings#release-v1-4&utm_source=blog#stop-words) and [synonyms](https://meilisearch.org.cn/docs/learn/configuration/synonyms#release-v1-4&utm_source=blog). Together, they synergize to improve the relevancy of the search results.

Let’s consider a literary database where an author's name may appear in various forms or abbreviations. This leads to fragmented search results, making it challenging for users to find works by that specific author. For example, take the different ways one might search for works by E. E. Cummings. Using the custom dictionary feature along synonyms can standardize these name variations, thereby enhancing the relevancy of search results.

Using synonyms and custom dictionary together, here’s an example of index settings that address this scenario:

```JSON
{
"dictionary": ["E. E.", "E.E.", "E E"],
"synonyms": {
    "E. E.": [ "E.E.", "E E", "Edward Estlin"],
    "E.E.": ["E. E.", "E E", "Edward Estlin"],
    "E E": ["E. E.", "E.E.", "Edward Estlin"],
    "Edward Estlin": ["E. E.", "E.E.", "E E"]
}
```

Breaking bug fix: improved filtering with backslashes
-----------------------------------------------------

In v1.4, we've addressed a longstanding bug that users faced when using backslashes (\\) at the end of the \`filter\` search parameter expression.

Let’s consider the following documents:

```JSON
[
  {
    "id": 1,
    "path": "my\\test\\path"
  },
  {
    "id": 2,
    "path": "my\\test\\path\\"
  }
]

```

**Note**: The double backslashes in the example are for JSON escaping.

Before v1.4.0, trying to filter on the second document using either of the filters `path = "my\\test\\path\\"` or `path = "my\\test\\path\\\"` would lead to errors.

Now, you can use any filter expression with backslashes. Just make sure to escape each `\` character in your filter.  

Using our example, to filter on the second document successfully, the filter should be written as: `path = "my\\\\test\\\\path\\\\"`.  

⚠️ **Warning:** If you're upgrading from v1.3.X or earlier and have previously used backslashes in filters, be aware that in v1.4.0, the correct filter for the first document should be `path = "my\\\\test\\\\path"`.  

Two layers of escaping are applied: : first, escape for JSON, then for the Meilisearch filter. Meilisearch turns `\\\\` back to `\\`, and JSON parsing will result in a single `\`.  

<Callout>
  Consider using built-in methods of your programming language to handle backslashes:- PHP: [addslashes() function](https://php.ac.cn/manual/en/function.addslashes.php)\- JavaScript: While JS doesn't have a specific method for adding slashes. You can use the [replace method](https://mdn.org.cn/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace), as suggested on [StackOverflow](https://stackoverflow.com/questions/7744912/making-a-javascript-string-sql-friendly)

What's new in v1.4?

Let's take a look at some of the most significant changes in Meilisearch's latest update. We’ll go over the main changes in this article, but you can also view the [full changelog](https://github.com/meilisearch/meilisearch/releases/tag/v1.3.0) on GitHub.

v1.3 is now available on [Meilisearch Cloud](https://meilisearch.org.cn/cloud), including all experimental features. Upgrade your Meilisearch instance in one click without downtime.

Experimental feature: vector search
-----------------------------------

<Callout>
  Using LangChain? You can now use the [Meilisearch vector store](https://python.langchain.ac.cn/docs/integrations/vectorstores/meilisearch) to benefit from powerful search features!
</Callout>

We are excited to introduce [vector storage](https://meilisearch.org.cn/docs/learn/experimental/vector_search)! Now, you can index and search documents using vector embeddings—numerical representations of data. For the first iteration of this feature, you need to use an external tool such as [Hugging Face](https://hugging-face.cn/), [Cohere](https://cohere.com/), or [OpenAI](https://openai.com/), to create such embeddings. Check out the [announcement post](/blog/vector-search-announcement/ to discover the extensive possibilities and potential applications of this feature.

<Callout>
  This feature is experimental, you can enable it using the new [experimental-features endpoint](https://meilisearch.org.cn/docs/reference/api/experimental_features).
</Callout>

To search documents based on their vector proximity, make sure they contain a `_vectors` field:

```bash
curl -X POST -H 'content-type: application/json' \
  'localhost:7700/indexes/songs/documents' \
  --data-binary '[
      { "id": 0, "_vectors": [0, 0.8, -0.2], "title": "Across The Universe" },
      { "id": 1, "_vectors": [1, -0.2, 0], "title": "All Things Must Pass" },
      { "id": 2, "_vectors": [[0.5, 3, 1], [-0.2, 4, 6]], "title": "And Your Bird Can Sing" }
  ]'
```

Once stored, you can search your vectorized documents by using the new `vector` search parameter in combination with the [search](https://meilisearch.org.cn/docs/reference/api/search) and [multi-search](https://meilisearch.org.cn/docs/reference/api/multi_search) routes.

```bash
curl -X POST -H 'content-type: application/json' \
'localhost:7700/indexes/songs/search' \
--data-binary '{ "vector": [0, 1, 2] }'
```

👉 Note that you need to generate the vector in your query using a third-party tool.

The returned documents include a `_semanticScore` field indicating the semantic similarity—or relevancy—of each document with the query.

```JSON
{
  "hits": [
    { "id": 0, "_vectors": [0, 0.8, -0.2], "title": "Across The Universe", "_semanticScore": 0.6754 },
    { "id": 1, "_vectors": [1, -0.2, 0], "title": "All Things Must Pass", "_semanticScore": 0.7546 },
    { "id": 2, "_vectors": [[0.5, 3, 1], [-0.2, 4, 6]], "title": "And Your Bird Can Sing", "_semanticScore": 0.78 }
  ],
  "query": "",
  "vector": [0, 1, 2],
  "processingTimeMs": 0,
  "limit": 20,
  "offset": 0,
  "estimatedTotalHits": 2
}
```
<Callout>
  This feature is experimental and we need your help to improve it! Share feedback on [this GitHub discussion](https://github.com/meilisearch/product/discussions/677).
</Callout>

New feature: display ranking scores at search
---------------------------------------------

Use the new `showRankingScore` search parameter to see the [ranking score](https://meilisearch.org.cn/docs/reference/api/search#ranking-score) of relevancy of each document:

```bash
curl \
  -X POST 'http://localhost:7700/indexes/movies/search' \
  -H 'Content-Type: application/json' \
  --data-binary '{ "q": "Batman Returns", "showRankingScore": true }'
```

Each document in the response will include a `_rankingScore` property, which represents a score between 0 and 1:

```JSON
"_rankingScore": 0.8575757575757575,
```

The higher the `_rankingScore`, the more relevant the document is.

Experimental feature: ranking score details
-------------------------------------------

For every document returned, Meilisearch provides a [detail of the ranking score](https://meilisearch.org.cn/docs/learn/experimental/ranking_rule_score_details) of each ranking rule. This feature is a perfect example of [how community engagement can enrich the design process](/blog/from-ranking-to-scoring/ at Meilisearch.

<Callout>
  This feature is experimental, you can enable it using the new [experimental-features endpoint](https://meilisearch.org.cn/docs/reference/api/experimental_features).
</Callout>

Set the `showRankingScoreDetails` search parameter to `true` to view the ranking score details:

```bash
curl \
  -X POST 'http://localhost:7700/indexes/movies/search' \
  -H 'Content-Type: application/json' \
  --data-binary '{ "q": "Batman Returns", "showRankingScoreDetails": true }'
```

  
The response should include the relevancy score of each rule:

```JSON
"_rankingScoreDetails": {
  "words": {
    "order": 0,
    "matchingWords": 1,
    "maxMatchingWords": 1,
    "score": 1.0
  },
  "typo": {
    "order": 1,
    "typoCount": 0,
    "maxTypoCount": 1,
    "score": 1.0
  },
  "proximity": {
    "order": 2,
    "score": 1.0
  },
  "attribute": {
    "order": 3,
    "attributesRankingOrder": 0.8,
    "attributesQueryWordOrder": 0.6363636363636364,
    "score": 0.7272727272727273
  },
  "exactness": {
    "order": 4,
    "matchType": "noExactMatch",
    "score": 0.3333333333333333
  }
}
```
<Callout>
  This feature is experimental. You can help us improve it by sharing your feedback on [this GitHub discussion](https://github.com/meilisearch/product/discussions/674).
</Callout>

New feature: search for facet values
------------------------------------

Once you have defined your [filterable attributes](https://meilisearch.org.cn/docs/reference/api/settings#filterable-attributes), you can use the new endpoint `POST /indexes/{index}/facet-search` to [search for facet values](https://meilisearch.org.cn/docs/learn/fine_tuning_results/faceted_search#searching-facet-values).

```bash
 curl \
  -X POST 'http://localhost:7700/indexes/movies/facet-search' \
  -H 'Content-Type: application/json'  \
  --data-binary '{
    "facetName": "genres",
    "facetQuery": "a"
  }'
```

  
As facet search is typo tolerant and supports prefix search, the above query will return de following results:

```JSON
{
    "facetHits": [
        {
            "value": "Action",
            "count": 5403
        },
        {
            "value": "Adventure",
            "count": 3020
        },
        {
            "value": "Animation",
            "count": 1969
        }
    ],
    "facetQuery": "a",
    "processingTimeMs": 0
}
```

New feature: sort facet values by count
---------------------------------------

By default, facets are sorted in ascending alphanumeric order. Now, you can sort facet values in descending order based on the number of matched documents containing each facet value.

To order facets by count, you can use the new `sortFacetValuesBy` property in the  [faceting index settings](https://meilisearch.org.cn/docs/reference/api/settings#faceting).

To modify the order for all facets, you can use the asterisk (\*) wildcard:

```bash
 curl \
  -X PATCH 'http://localhost:7700/indexes/movies/settings/faceting \
  -H 'Content-Type: application/json'  \
  --data-binary '{
    "sortFacetValuesBy": {"*": "count"}
  }'
```

Alternatively, you have the flexibility to order a single facet by count while maintaining alphanumeric ordering for other attributes:

```json
 curl \
  -X PATCH 'http://localhost:7700/indexes/movies/settings/faceting \
  -H 'Content-Type: application/json'  \
--data-binary '{
    "sortFacetValuesBy": {"*": "alpha", "genre": "count"}
  }'
```

You can also try it in the [ecommerce demo](https://ecommerce.meilisearch.com/).

New feature: searchable attributes at query time
------------------------------------------------

With the new `attributesToSearchOn` search parameter, you can now [restrict the search](https://meilisearch.org.cn/docs/reference/api/search#customize-attributes-to-search-on-at-search-time) to a subset of the [searchable attributes](https://meilisearch.org.cn/docs/learn/configuration/displayed_searchable_attributes#the-searchableattributes-list) at query time. It accepts an array of strings indicating one or more document attributes:

```JSON
{
  "q": "adventure",
  "attributesToSearchOn": ["genre"]
}
```

Given the following documents, the above query will only return document with id 1.

```JSON
{
    "id": 0,
    "name": "An Adventure in Space and Time",
    "genre": ["drama"]
},
{
    "id": 1,
    "name": "A Strange and Stubborn Endurance",
    "genre": ["adventure"]
}
```

Relevancy change: attribute ranking rule
----------------------------------------

With v1.3, the [attribute ranking rule](https://meilisearch.org.cn/docs/learn/core_concepts/relevancy#4-attribute) assigns higher relevancy to documents where the query words appear closer to their position in the query, compared to documents where the query words are farther from their position in the query.

Before, this rule measured relevancy based on the position of the words in the attribute rather than on their position in the search query. Documents with attributes containing the query words at the beginning of the attribute were considered more relevant.

Consider the following query: "Batman the dark knight returns" and the corresponding documents:

```JSON
{ 
    "id": 0, 
    "title": "Batman the dark knight returns" 
},
{ 
    "id": 1, 
    "title": "Dark the Batman knight returns" 
},
{ 
    "id": 2, 
    "title": "Batman returns: a retrospective", 
    "description": "The Dark knight is analyzed in this new Batman documentary" 
}
```

Prior to version 1.3, the attribute ranking rule placed document 2 at the top of the list, followed by documents 0 and 1, ranked in a tie.

Since version 1.3, the order is strictly: document 0, document 1, document 2, which provides a more natural ranking.

Other improvements
------------------

*   The `/tasks` route now shows the total number of tasks in the queue using the `total` property. It also displays the total number of tasks based on specific filters
*   Enhanced Japanese support and segmentation
*   Improvements in the Prometheus `/metrics` experimental feature
