Advanced RAG techniques with Spring AI

Spring AI offers advanced features for Retrieval Augmented Generation (RAG) to enhance LLM responses with domain-specific knowledge. These features include document loading using TikaDocumentReader, advanced query processing with MultiQueryExpander and CompressionQueryTransformer, and custom document processing via RetrievalAugmentationAdvisor. Error handling and safety measures, like SafeguardAdvisor, can be implemented to ensure robust, production-ready applications.
