Covers why keyword search falls short, how embeddings place semantically similar text close together in vector space, how cosine similarity measures that closeness, and how all of this powers the retrieval step in a RAG (Retrieval-Augmented Generation) pipeline. Uses plain-language analogies and a concrete RAG pipeline walkthrough to make the concepts accessible without heavy math. ## Full article daily.dev links to this article rather than hosting it.
