14 points · Open discussionYou Do Not Need a Vector Database (For RAG): Benchmarking IR Methods
The document retrieval problem for RAG is basically a case for information retrieval
and there are simpler solutions to do so. Vector embeddings are still useful,
but they should be used in a later stage of the IR pipeline and not as the
first stage retrieval, for which there are simpler and more performant solutions.
