NEW Making RAG Conversation-Aware

Making RAG Conversation-Aware

RAG works best when it understands the conversation, not just the latest question. In this recipe, you'll teach Spring AI to fold relevant chat history into vector store queries so follow-up questions retrieve the right context every time.

NEW RAG Without a Separate Vector Database

RAG Without a Separate Vector Database

RAG doesn’t have to mean deploying and maintaining a separate vector database. In this recipe, you’ll learn how to build a fully functional Spring AI RAG application using an in-JVM vector store that keeps everything inside your application.
