Retrieval Augmented Generation With Spring AI 2.0, Claude, and PGvector

Language models become much more useful when they can answer questions about information they were never trained on, including your internal documentation, product manuals, policies, and other proprietary data. Prompting alone cannot solve this, because the model simply does not have access to that knowledge. Retrieval-Augmented Generation, or RAG, is the most common way to bridge that gap.
