# GraphRAG: The End-to-End Guide to Reducing Hallucination and Automating Complex Workflows
GraphRAG is an advanced retrieval-augmented generation technique designed to overcome the limitations of standard vector RAG, particularly for complex, multi-hop, or global questions. Unlike vector RAG which relies on semantic similarity of text chunks, GraphRAG builds a knowledge graph of entities and their relationships during an indexing phase. This graph is then used during querying to traverse connections between information, enabling more accurate answers for questions that require synthesizing information across multiple documents or understanding causal links.
