[AI Search](/ai-search/) now carries each localized sitemap page's self-referencing `hreflang` value into its indexed `language` metadata. Retrieval filters on `language` can now match localized website content in both vector and keyword search.

If a page also defines a configured `language` field in its HTML custom metadata, the HTML value continues to take precedence. The next source sync reindexes localized pages to apply the metadata fix.

For more information, refer to [website data sources](/ai-search/configuration/data-source/website/) and [metadata filtering](/ai-search/configuration/retrieval/filtering/).
