Hi all, I was looking at this idea for some experimentation ideas (not mean to be intrusive to ongoing effort). If the full sized vectors are exposed through `getFloatVectorValues` then it seems we can just call exactSearch over the results of approximateSearch, but this would inefficiently re-rank `k * oversample * num_segments` instead of just `k * oversample` (with some improve in recall perhaps). However I don't know how to get the full-sized vectors without LeafContextReader. Do you have an idea how we can achieve that? Or maybe we can just reduce oversample to account for the number of segments, e.g: `oversample = oversample / leafReaderContexts.size()` (which maybe differs)? -- This is an automated message from the Apache Git Service.
