Use `/ai-search/namespaces/default/instances/{id}/search`. The un-namespaced and `/autorag/rags/` paths are deprecated\n2. Set `ai_search_options.retrieval.max_num_results` (1 to 50, default 10) and `match_threshold` (default 0.4) to bound the context you read\n3. On 429 code 7069 the monthly query quota is spent. Wait or upgrade rather than retry\n4. Expect up to six hours before website or R2 changes are searchable. Trigger a sync job, at most once every 30 seconds, after you write\n5. Filters match only the first 64 bytes of a string. Use a `$gte`/`$lt` range on `folder` to match a folder and its subfolders\n\n### Epsilla Vector Database\n\n1. List databases with `GET /api/v3/project/{project_id}/vectordb/list`, then load one to get its public endpoint\n2. Hybrid search is assembled client-side with `as_search_engine().add_retriever(...).set_reranker(type=\"rrf\")`\n3. If you use pyepsilla against the cloud, patch or wrap it to verify TLS\n4. Ask a person to create the database in the console first.
