โ ๏ธ Breaking Changes & Deprecations (1)
- - Small breaking change: a few error codes change, such as `MultiSearch<Error>` <--> `Search<Error>`
โจ New Features & Capabilities (3)
- We now better support the tokenizer-related settings
- We improved the quality of the new settings indexer to enhance the engine's performance when changing the locales, the dictionary, synonyms, stop words, separator, and non-separator tokens.
- This makes the new settings indexer feature-complete, meaning that, unless you set the `MEILI_EXPERIMENTAL_NO_EDITION_2024_FOR_SETTINGS` environment variable to `true`, all settings tasks can now be handled by the new settings indexer, bringing a better scaling behavior, much faster cancellation, and a more precise progress view.
๐ง Bug Fixes & Patches (3)
- Putting attributeRank/ wordPosition before words in the rankingRules list will no longer remove hits from the response,
- Meilisearch will no longer ignore the `searchCutoffMs` in some conditions when embedding documents,
- Meilisearch will no longer fail to proxy a search request with a filter containing a `'` during remote federated search or `useNetwork: true` search requests,

# ๐ Enhancements
## Search personalization on federated search
We now support using the [search personalization feature](https://www.meilisearch.com/docs/capabilities/personalization/overview) on federated search requests.
Like `page`/`hitPerPage` or `limit`/`offset`, the personalization option must be specified in the federation attribute to work properly.
Otherwise, an error will be returned reminding you to move the attribute in federation.

## Observability improvements
We expose more Prometheus metrics to improve observability, specifically to show more metrics on document throughput and ease debugging.

# ๐ฉ Misc. changes
## Search implementation refactor
Refactor the search pipeline to mutualize the code.
The new implementation will always perform a federated search under the hood, and then the output will be transformed into the expected route's output.
Noticeable changes from the user perspective:
- Some error messages have been modified
- Small breaking change: a few error codes change, such as `MultiSearch<Error>` <--> `Search<Error>`
## Other changes
- Make it easier and less error-prone to declare a type that is used as a body parameter on a Meilisearch endpoint, by @dureuill in https://github.com/meilisearch/meilisearch/pull/6429
- Remove the now unused `vectorStoreBackend` setting from the settings, by @Kerollmops in https://github.com/meilisearch/meilisearch/pull/6399
