Learn how to overcome common RAG challenges including inaccurate answers, poor document retrieval, and ineffective text chunking using LangChain4j. Discover advanced techniques including optimized document segmentation strategies, query refinement methods for improved retrieval accuracy, effective metadata filtering, document reranking for better result presentation, agentic approaches utilizing function calling, data lifecycle management processes, and comprehensive evaluation methods. Transform frustrating RAG experiences into systems that consistently delight users with accurate, relevant answers. The 53-minute Devoxx presentation by Guillaume Laforge provides practical guidance for developers looking to elevate their RAG implementations beyond basic functionality.
