UnverifiedRAG has evolved into iterative RAG variants (such as FLARE and Self-RAG), Graph RAG, and hybrid retrieval schemes that combine BM25 with semantic vectors.69% similarUnverifiedThe core engineering pipeline of a RAG system includes document chunking strategy, embedding model selection and vector database deployment, hybrid retrieval (semantic retrieval + BM25 keyword retrieval), and Reranker reranking.65% similarUnverifiedThe selection of vector databases and chunking strategies (chunk size, overlap) have a significant impact on RAG retrieval quality.64% similar
