Stop Using Top-K Retrieval. Try This Instead. Everyone talks about RAG like the hard part is the generation. It's not. The hard part is getting the right chunks in front of the model in the first place. I've written before about why RAG retrieval is really a filtering problem, not a search problem , and this experiment confirmed it. I learned this the hard way.
