A RAG system first splits documents and converts them into vector embeddings, then retrieves via measures such as cosine similarity; similarity measures semantic closeness, not factual correctness.

VerifiedThe RAG strategy encodes code snippets as high-dimensional semantic vectors through vector embeddings, and during retrieval computes the semantic similarity between query intent and code snippets to recall relevant code.80% similarUnverifiedIn RAG, the question and the knowledge base must be vectorized using the same embedding model for vector similarity to effectively represent text similarity.79% similarUnverifiedRAG pipelines usually involve steps such as document chunking, vector embedding, similarity retrieval, and prompt assembly.76% similarUnverifiedThe fundamental mechanism of RAG (Retrieval-Augmented Generation) is similarity matching, which excels at finding semantically similar text but is powerless against structured business logic.75% similar
