EDITOR'S TAKE

Vector DB with strong hybrid search (vector + keyword) and built-in modules for common embedding workflows. Slightly higher learning curve than Qdrant but powerful for production RAG.

Use this if

You need hybrid keyword + vector search and want it built in rather than bolted on.

Skip if

You only need pure vector search — Qdrant is simpler.
