The RAG Compass

What to expect

Everything in retrieval maps to one mental model, the five station compass, and this volume walks it end to end. It moves from the simplest baseline to agentic retrieval, weighs vector, graph, and vectorless approaches, tears down how real companies run RAG in healthcare, legal, and finance, and names the places where people usually go wrong. It closes with a 45 question interview dojo so you can test yourself on all of it.
