Detailed answer
Use RAG Pipeline Overview as the core idea. Example shape: HR chatbot retrieves policy PDFs chunks then answers with footnotes.. Watch for: Garbage retrieval → garbage answers.. Measure success via latency/error/saturation. Core: Ingest → chunk → embed → index (vector DB) → retrieve top-k → (rerank) → prompt LLM with context → answer + citations. Separates knowledge from model weights. Real-time example: HR chatbot retrieves policy PDFs chunks then answers with footnotes. Pros: Updatable knowledge without retrain; more grounded. Cons: Garbage retrieval → garbage answers. Common mistakes: Huge chunks; no metadata filters; stuffing irrelevant context. Best practices: Evaluate retrieval and answer separately; hybrid search. Audience level: Mid-level.
