# V3 Query API

* **[Query - v3](/reference/v3/query)**: new File Search query endpoint for retrieved source chunks with `results[].text`, document context, metadata, regions, relations, related chunks, and explicit rerank status.
* **Cleaner request controls**: use `filter` for metadata and custom metadata constraints, `include` to opt into extra response context, and relation parameters to retrieve graph context with search results.
