Roaming RAG – RAG without the Vector Database

In much of the public discourse, RAG has been almost synonymous with Semantic Search. And while Semantic Search is a reasonable choice for plenty of RAG applications, it's often overkill.

In this post, I present Roaming RAG, a novel form of Agentic RAG, which lets the agent navigate the corpus in much the same way that a human would – by reading the table of contents. This means that you don't even need retrieval – no embedding models, no infrastructure, no ETL.
