VerifiedThe GraphRAG approach extracts entities and relationships from documents, stores them as nodes and edges in a graph database, and during retrieval first uses vector search to recall candidate nodes before performing multi-hop reasoning along the graph's edges.76% similarUnverifiedAgentic GraphRAG Blueprint builds a knowledge graph and combines it with vector search, enabling answers to connect facts across multiple documents.71% similarVerifiedThe core of GraphRAG is integrating knowledge graphs into the traditional RAG pipeline, organizing information in the form of triples (two entities and their relationship).68% similarUnverifiedGraph databases store relationships as first-class citizens, enabling multi-hop relationship queries to be completed in milliseconds via graph traversal algorithms without the need to perform costly multi-table JOIN operations.64% similar
