When you talked about "document index is a hybrid index of keyword frequencies and vectors", I am a bit curious of how to get them. In pre-processing, do you have to use LLM / models go through documents to get keywords? What about vectors? Are you using embed model to generate them? Does that imply preprocess has to be done whenever there is new doc or any modification in existing doc? Would that be costly in time? Any spicy cook to make the preprocessing more efficient?
