Added
- Added multimodal File Search RAG support using gemini-embedding-2.
- Added image file sync support for RAG stores: PNG, JPG, and JPEG.
- Added custom metadata to synced RAG files: path, extension, basename, folder, modified time, and size.
- Added an optional metadata filter field for Semantic Search settings.
Changed
- New internal File Search stores are created with multimodal embeddings.
- Existing or unknown legacy RAG stores now prompt during sync to either keep using the current store or recreate it
with gemini-embedding-2. - File Search store IDs are normalized to fileSearchStores/... before API calls.
- RAG sync now waits for upload/indexing operations to complete before marking files as synced.
- Semantic Search selection is resolved directly from the current UI setting to avoid stale workspace state.
Notes
- Interactions API uses File Search correctly, but it currently returns only signed File Search results to the client,
not retrieved source titles or text. Because of that, the UI can reliably show that RAG was used, but source
excerpts may not be available from this API path.
