[ { "question": "What is Retrieval-Augmented Generation (RAG)?", "expected_answer": "RAG is a technique that combines information retrieval with language model generation. Instead of relying solely on a model's parametric knowledge, RAG retrieves relevant documents from an external knowledge base and uses them as context for generating answers.", "relevant_sources": [], "collection": "default" }, { "question": "What chunking strategies are available in this RAG system?", "expected_answer": "The system supports three chunking strategies: recursive character splitting (default), semantic chunking based on embedding similarity, and hierarchical parent-child chunking for multi-granularity retrieval.", "relevant_sources": [], "collection": "default" } ]
