VerifiedThe effectiveness of RAG is highly dependent on the quality of the document chunking strategy: chunks that are too long increase retrieval noise, while chunks that are too short lose contextual semantics.71% similarUnverifiedRAG中检索召回率与精确率之间存在固有权衡，检索过多文档引入噪声，检索过少遗漏关键信息68% similarUnverifiedThe RAG pipeline involves multiple stages including document chunking strategy, vectorization method, retrieval algorithm, re-ranking, and prompt templates; a problem in any single stage will affect the quality of the final answer.68% similarUnverifiedRAG的质量往往卡在最前端的文档解析阶段，简单文本提取会破坏表格、标题层级和脚注等结构导致语义向量失真65% similar
