Correct. RAG is a general term as you describe, but it has become inextricably linked with vector databases in the minds of a lot of people, to the extent that GP and even the blog post we're discussing use RAG specifically to mean the use of a vector database after chunking input to create embeddings.

I agree with you that RAG should be a generic term that is agnostic to the method of retrieval and augmentation. But at the moment, in a lot of people's minds, it specifically means using a vector database.
