RAG

Production guides and engineering blueprints for Retrieval-Augmented Generation (RAG) and semantic vector search in Python. Master enterprise vector retrieval using PostgreSQL and pgvector, implement hybrid search combining BM25 keyword matching with dense vector embeddings, conquer complex PDF layout chunking for multi-column documents and tables, and dramatically boost search precision using cross-encoder reranking models.
