GraphRAG: A Practitioner's Guide to 6 Advanced Architectural Patterns
By vectorizing documents and retrieving semantically similar chunks at query time, RAG mitigates hallucinations, grounds responses and bypasses static knowledge cutoffs imposed by model pretraining. However, in a real-life scenario, standard vector-based RAG runs into limitations for complex queries, such as those that require global context, multi-hop reasoning, cross-document aggregation of numerical figures etc. Standard RAG is great at answering explicit, localized queries.
