Reference
The GrowlerDB API and query surface:
- Query language — the Lucene/KQL string syntax and the field types it operates on.
- REST & gRPC API — the Engine API endpoints the gateway serves.
- OpenSearch adapter — the optional, read-path
_searchcompatibility layer.
The console UI is a pure client of this same API — anything the UI does, a programmatic caller can do over REST/gRPC.
