Filter PgVector results by minimum similarity score

PgVector now accepts a similarity_threshold parameter, letting you set a quality floor for search results. Low-relevance matches are excluded at the database level, so agents only work with results that meet your precision requirements.

Details

  • New similarity_threshold parameter on PgVector search operations
  • Reduces noise in retrieval pipelines and improves downstream answer quality
  • No migration required; add the parameter where needed
