A practical roadmap for modern AI search and Retrieval-Augmented Generation (RAG) systems emphasizes the need for robust, real-world applications beyond basic vector databases and prompts. Key components include semantic and hybrid retrieval methods, explicit reranking layers, and advanced query understanding and intent recognition. The roadmap also highlights the importance of agentic RAG, which involves query decomposition and multi-hop processing, as well as maintaining data freshness and lifecycle management. Additionally, it addresses grounding and hallucination control, evaluation criteria beyond superficial correctness, and production concerns such as latency, cost, and access control. This roadmap is designed to be language-agnostic and focuses on system design rather than specific frameworks. Understanding these elements is crucial for developing effective and efficient AI search systems that meet real-world demands.
