+### Fixed

+- **Chat search broken (silent 422 error)** — The search bar sent `limit=1000` but the API enforced `le=500`, causing FastAPI to reject every search request with a 422 validation error. The frontend silently swallowed the error, making search appear to return no results. Raised the API limit to 1000 to match the frontend.
+- **Chat search ignored in DISPLAY_CHAT_IDS mode** — When `DISPLAY_CHAT_IDS` was configured, the search query was never passed to the database, so typing in the search bar had no effect on the displayed chats.
