Improving RAG Systems - Key Challenges and Solutions
summary
States that RAG remains fundamentally a search problem and lists concrete failure points: missing content, mis‑top ranking, incomplete extraction, hallucinations and bad formatting. Recommends specific fixes: better chunking and embeddings, semantic thresholding plus keyword hybrid search, rerank models, agentic RAGs that call tools/external web and a basic agentic RAG prototype that retrieves internet facts, contextual compression (Microsoft prompt compression), multi‑query retrieval, hypothetical document embedding, and using ChatGPT 40 mini or output parsers for reliable JSON.
