@vigyasharma Answering other questions: > We seem to consistently see an improvement in recall between single segment, and multi-segment runs (both seq and conc.) on baseline. Is this because with multiple segments, we get multiple entry points into the overall graph? Whereas in a single merged segment, we only have access to a sparser set of nodes in layer-1 while finding the single best entry point? Indeed, this is the correct observation. For multiple segments, we retrieve k results from each segment, and then merge k* num_of_segments results to get the best `k` results. As we are retrieving more results, we also get better recall than from the single segment. -- This is an automated message from the Apache Git Service.
