Beyond Naive RAG: Build Smarter Systems with Query Routing and Hybrid Retrieval

What this post added

This post introduces advanced techniques for building smarter RAG systems, focusing on query routing and hybrid retrieval. It proposes a four-node architecture for query classification, rewriting, retrieval strategy selection, and minimal-context generation. It also details how to implement unified hybrid retrieval using Milvus 2.6, which supports dense and sparse vectors in the same collection, and outlines a stage-by-stage evaluation methodology for RAG pipelines.
