Hybrid Retrieval in RAG: Combining Dense Vectors, Sparse Vectors, Full-Text Search, and Tensor Re-ranking for Optimal Performance

In modern Retrieval-Augmented Generation (RAG) systems, hybrid search strategies combine multiple retrieval methods to enhance accuracy. The architecture typically integrates dense vectors, sparse vectors, full-text search, and tensor-based re-ranking mechanisms. Why Multi-Path Recall Matters Traditional dense vector search alone often fails to ...
