Simon Eskildsen(@Sirupsen):BM25 (least compute) sparse vector regex dense vector late interaction (most compute) we will index every byte. you simply choose how much compute you want to spend indexing, based on your read:write ratio.

tpuf now supports late interaction [beta] use models like ColBERT to represent text as a set of vectors (1 per token) tpuf uses a single-vector ANN index for a fast first pass, then reranks hits using exact late interaction scoring to boost recall docs:
