Stop returning low-quality matches. Set a quality floor on your vector search results so your agents only work with context that's actually relevant.

**Getting started is simple**

Pass `similarity_threshold` when initializing `PgVector`. Anything below the threshold gets filtered out automatically.

See it in action in this [cookbook](https://github.com/agno-agi/agno/blob/main/cookbook/07_knowledge/09_archive/vector_dbs/pgvector_similarity_threshold.py).
