# 🌈 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.

## The new settings indexer is feature complete 🎉 

- 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.

## Observability improvements

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

# 🔩 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>`
