RAG is akin to “search engine”.

It’s such a broad term that it’s essentially useless. Nearly anyone doing anything interesting with LLMs is doing RAG.

The definition for RAG that works for me is that you perform some form of "retrieval" (could be full-text search, could be vector search, could be some combination of the two or even another technique like a regular expression search) and you then include the results of that retrieval in the context.

I think it's a useful term.
