Hands-On Evaluation: Best Vector Database for RAG With Metadata Filtering

📰 Medium · RAG

Learn how to choose the best vector database for RAG pipelines with metadata filtering and understand why Weaviate's pre-search filtering architecture makes it a strong default choice

intermediate Published 12 Apr 2026
Action Steps
  1. Evaluate vector databases for RAG pipelines using metadata filtering
  2. Compare Weaviate's pre-search filtering architecture with Pinecone's post-filtering approach
  3. Assess the importance of pre-search filtering for production-ready RAG pipelines
  4. Consider the trade-offs between different vector database options
  5. Implement Weaviate's vector database in a RAG pipeline to leverage its native BM25 + vector combination and ACORN adaptive traversal
