[counterintuitive] Should I put all retrieved documents into the LLM context window

Limit context to only highly relevant chunks and place the most critical information at the very beginning or end of the prompt; use RAG re-ranking to minimize the context length.

Journey Context:
With the advent of large context windows, developers often stuff dozens of retrieved documents into a prompt assuming more information yields better answers. Research proves models suffer from 'Lost in the Middle' degradation: they attend strongly to the beginning and end of the context but ignore or forget information in the middle. Stuffing the prompt increases latency, cost, and distracts the model, actually reducing accuracy compared to a leaner, well-ranked context.
