VerifiedHybrid Search combines dense vector semantic similarity with BM25 sparse keyword matching, with results from both paths re-ranked by a Re-Ranker model before being injected into the LLM context.79% similarUnverifiedMulti-route recall means simultaneously using multiple retrieval strategies (such as vector retrieval, BM25 keyword retrieval, knowledge graph retrieval, etc.) to recall candidate sets separately, then merging and deduplicating them for unified re-ranking, to compensate for the blind spots of any single retrieval method.78% similarVerified混合检索（Hybrid Search）将向量检索与BM25关键词检索的结果通过RRF（倒数排名融合）等算法合并，兼顾语义理解与精确匹配77% similar
