Learn to design a RAG database with SQL, full-text search, vector search, and context retrieval for efficient information retrieval

intermediate Published 23 Jul 2026
Action Steps
  1. Design a SQL database schema for RAG using entity-relationship modeling
  2. Implement full-text search using BM25 algorithm for keyword-based queries
  3. Configure vector search for semantic search and similarity-based queries
  4. Apply reranking techniques to improve search result relevance
  5. Test and optimize the RAG database for security, cost, and locality-aware context retrieval
