Summary
A paper introduces a 5-step blueprint for optimizing RAG pipelines by greedily selecting interchangeable modules per node on the user's own dataset, emphasizing that best performing pipelines are dataset-specific rather than benchmark-driven.

This paper completely changed how I think about assembling a RAG pipeline:
Define the nodes -> List candidates for each -> Run them on your dataset -> Keep the winner -> Move to the next node
Here is the 5-step blueprint:
Nodes: the pipeline is split into stages - query expansion, retrieval, augmenter, reranker, prompt maker.
Candidates: each node gets a set of interchangeable modules - BM25, vectordb, hybrids, rerankers.
Greedy per node: you optimize nodes one at a time, locking the best module before moving on.
Two metrics: retrieval is measured separately from generation, so you see exactly where quality leaks.
On your own data: the optimum is searched on your corpus, not a foreign leaderboard - the best module for Wikipedia QA fails on domain docs.
Key insight: the best RAG pipeline is not picked from a benchmark, it is found by search on your own dataset.
Five pipeline stages, each with a pool of interchangeable modules, and the loop assembles the winning combination on its own.

A benchmark comparing 18 RAG pipeline variants against a simple agent loop on Google's FRAMES multi-hop questions finds the best pipeline hits 78.9% while an agentic loop that can re-search reaches 92.7%, with surprising results showing reranking often hurts accuracy. The authors also note models sometimes fill gaps from memory despite instructions to stick to retrieved documents.
