From RAG to GraphRAG: How Huolala Raised Metadata Retrieval Accuracy from 56% to 78%
The article details Huolala's transition from a basic Retrieval‑Augmented Generation (RAG) system to a GraphRAG architecture, explaining the challenges of traditional RAG, the design of offline and online stages, multi‑index hybrid search, concrete performance metrics (accuracy up to 78%, knowledge recall 91%, Top‑K 90%, MRR 0.73), and future plans such as stronger hybrid retrieval, reranking, and Agentic RAG.
