A new research paper details DocuSearch, an enterprise document search system designed to improve accuracy and grounding for complex queries. DocuSearch integrates semantic search with BGE-Large embeddings, BM25 full-text search, and knowledge graph expansion. These retrieval methods are combined using Reciprocal Rank Fusion, followed by cross-encoder reranking and Maximal Marginal Relevance pruning. A key innovation is its per-chunk evaluation loop, where an LLM assesses context, answer completeness, and grounding, ensuring only reliable information is returned. AI
IMPACT This system could significantly improve the reliability and accuracy of information retrieval in enterprise settings by integrating multiple search techniques and an LLM-based grounding evaluation.
