Inside RAG — the pipeline
Learn the controls and knobs
Each RAG pipeline stages control is a hypothesis about a metric under a workload—not a synonym for quality on the vacation-policy Q&A.

Look up trusted notes first — then answer with that context
Primary knobs for RAG pipeline stages: chunk size, embedding model, hybrid weights, top-k, reranker, context budget, citation format.
Write a sheet for the vacation-policy Q&A with columns: control, current value, predicted benefit, predicted cost, rollback trigger. Fill it using this topic’s real tension: Small chunks retrieve precisely but lose surrounding context; large chunks preserve context but dilute matches. Higher top-k improves recall while adding distractors and tokens. Reranking improves ordering at extra latency. Fresh indexing costs compute but stale evidence damages trust.
Change one RAG pipeline stages family at a time. If you move two knobs and the vacation-policy Q&A improves, you learned a cocktail, not a cause—and you cannot roll back surgically.

Product exposure
End users of the vacation-policy Q&A should see only safe dials related to RAG pipeline stages. Infrastructure limits, private prompts, and policy thresholds stay server-owned. A user-facing control that bypasses those limits is a vulnerability dressed as UX for RAG pipeline stages.

Make it operational
Publish the RAG pipeline stages control sheet next to the vacation-policy Q&A runbook. On-call should see which knob moved in the last deploy without reading chat archaeology. Unknown RAG pipeline stages knobs are unowned knobs.
Also pin one numeric memory from this RAG pipeline stages chapter: if 18 of 20 test questions retrieve at least one relevant chunk in top 5, recall@5 = 18/20 = 0.90 That number is not decoration; it is a template for how claims about RAG pipeline stages on the vacation-policy Q&A should look in design docs.

Common mix-ups
People confuse RAG pipeline stages with neighboring buzzwords when debugging the vacation-policy Q&A. Before changing prompts, ask whether the broken stage was evidence gathering, the RAG pipeline stages judgment itself, validation, or the product action. Fixing the wrong stage creates folklore (“we tried RAG pipeline stages and it failed”) that blocks the next team on the vacation-policy Q&A.

Write a five-line artifact for this page: goal, inputs, check, owner, stop rule. Invent one fluent failure that the check would catch. Keep details specific to rag pipeline steps rather than generic AI advice.

Why this matters
From [chunk size, embedding model, hybrid weights, top-k, reranker, context budget, citation format], pick one control for RAG pipeline stages on the vacation-policy Q&A. Predict which metric rises and which cost rises if you increase it.
