1. What is RAG

RAG stands for Retrieval-Augmented Generation. That’s a mouthful, so let’s break the phrase into its three pieces because each word actually tells you exactly what’s happening.

1. Multi-Document RAG

Basic RAG, in its simplest form, is often explained as if you’re searching through one big pile of text and pulling out a few relevant chunks. But in reality, most useful RAG systems need to work across many separate documents — sometimes hundreds, thousands, or more — and the answer to a question might require pulling together pieces from several completely different documents at once.

1. Vector Database Architecture

Let’s start by understanding, at a high level, what’s actually happening inside a vector database, because this foundation will make everything else in this guide much easier to follow.
