UnverifiedAdvanced RAG introduces Query Rewriting and HyDE (Hypothetical Document Embeddings) before retrieval to optimize query quality, and improves relevance after retrieval through Cross-Encoder re-ranking and context compression.75% similarUnverifiedQuery Rewriting solves the problem of users' questions being colloquial and having unclear references, and common methods include using a large model to rewrite the question into a formulation more conducive to retrieval, expanding a single-turn question into multiple related sub-questions, and completing the context based on historical conversation.74% similarUnverifiedQuery2doc achieves LLM-based query expansion by generating short paragraphs, while HyDE does so by generating hypothetical documents.70% similarUnverifiedDifferent conversational agents employ differentiated complex query strategies to decompose, rewrite, and combine search keywords.69% similarUnverifiedQuery rewriting can transform an agent's natural language reasoning fragments into a search-engine-friendly format, thereby improving recall.68% similar
