# Query Decomposition Break complex queries into independent concepts for parallel retrieval and fusion. ## Overview - Complex queries spanning multiple topics or concepts - Multi-hop questions requiring chained reasoning - Queries where single retrieval misses relevant documents - Improving recall for compound questions Break complex queries into independent concepts for parallel retrieval and fusion. ## The Problem Complex queries span multiple topics that may not co-occur in single documents: ``` Query: "How do chunking strategies affect reranking in RAG?" → Single search may miss docs about chunking OR reranking → Poor coverage across all concepts ``` ## The Solution Decompose into independent concepts, retrieve separately, then fuse: ``` Query: "How do chunking strategies affect reranking in RAG?" → Concepts: ["chunking strategies", "reranking methods", "RAG pipeline"] → Search each concept independently → Fuse results with Reciprocal Rank Fusion (RRF) → Full coverage across all topics ``` ## Implementation ### 1.
