RAG Retrieval Optimization: Reduce Vector Search Before Ranking

📰 Dev.to · puffball1567

Optimize RAG retrieval by reducing vector search space with metadata filtering, tenant scope, and data locality

intermediate Published 3 Aug 2026
Action Steps
  1. Apply metadata filtering to narrow down the search space
  2. Configure tenant scope to limit the search to specific tenants
  3. Implement data locality to reduce the amount of data that needs to be searched
  4. Test the optimized RAG retrieval with sample queries
  5. Compare the performance of the optimized retrieval with the original implementation
