# LightRAG

Graph-based RAG framework (HKUDS) that extracts entities and relations from documents via LLM, builds a persistent knowledge graph, and supports multiple retrieval modes (naive, local, global, hybrid, mix). Used in this wiki as the graph indexing layer alongside qmd. See [Wiki Indexing Pipeline: qmd and LightRAG](https://vietbui.mintlify.site/systems/wiki-indexing-pipeline.md) for operational details and [Local Wiki RAG: LightRAG Graph Stack](https://vietbui.mintlify.site/syntheses/local-rag-wiki.md) for the two-path stack.
