Summary

When putting the following Language settings:

{
   "localizedAttributes": [
      {"locales": ["jpn"], "attributePatterns": ["*"]}, 
   ]
}

Saying, "Everything is Japanese."

Then Meilisearch should be able to 100% detect Japanese without having to specify it at search time:

{
  "q": "進撃の巨人",
  "locales": ["jpn"]
}

See the related PRD:

Technical Approach

In execute_search the locals are only taken from the search parameter, but if the locales are set to None, Meilisearch should be able to use the stored localized_attributes_rules to determine a subset of detectable languages.

TODO

• Make Meilisearch use the stored localized_attributes_rules to auto-detect Language at search time
• add tests
