Knowledge graphs and vector search are related as complementary retrieval techniques within GraphRAG, where vector search is used to identify initial relevant information [1] while the knowledge graph provides structural context that vector search alone lacks {fact:1, fact:2, fact:3}.

claimGraphRAG is a retrieval-augmented generation (RAG) technique that incorporates a knowledge graph to enhance language model responses, either alongside or in addition to traditional vector search.
claimBasic RAG techniques retrieve isolated pieces of information using vector search, whereas GraphRAG utilizes a knowledge graph to understand how facts are linked.
claimGraphRAG addresses the limitations of traditional vector search by combining Retrieval-Augmented Generation (RAG) with a knowledge graph, which is a data structure representing real-world entities and their relationships.
procedureGraphRAG retrieval can begin with vector, full-text, spatial, or other types of search to find relevant information in a knowledge graph, then follow relationships to gather additional context needed to answer a user's query.
