The Evolution of Agentic Search: From Naive RAG to Reasoning-Driven Retrieval

As Large Language Models (LLMs) transition from simple chatbots to autonomous agents, the methods we use to feed them data must evolve. While Retrieval-Augmented Generation (RAG) remains the industry standard for grounding models in external data, its “vanilla” implementation—converting text chunks into vectors for semantic lookup—often falters when faced with interconnected documents, technical jargon, or multi-hop queries. For Machine Learning Engineers (MLEs) and Product Managers (PMs), understanding the shift toward Agentic Search is critical. This approach moves away from static lookups toward dynamic, iterative, and hierarchical strategies that mirror how a human expert navigates a complex knowledge base. ...
