List search filters
GET/api/search/filters
Expect changes and instability. Introduced on May 12, 2026. Learn how experimental APIs work.
List datasources and common built-in filter fields visible to the authenticated user. This is a best-effort catalog, not an exhaustive list of every filter search accepts.
Without query, returns field metadata only and does not run a search. With a nonblank query, provide exactly one datasources value to request suggested filter values for that query; no documents are returned and this endpoint does not include warning objects. See FilterFieldInfo.values for limitations on suggested values. Rate-limited requests return HTTP 429 with Retry-After; temporary backend unavailability returns HTTP 503.
