> If IndexSearcher is configured with an executor, then the top docs for each slice are computed separately before being merged once the top docs for all slices are computed. With block-max WAND this is a bit of a waste of resources: it would be better if an increase of the min competitive score could help skip non-competitive hits on every slice and not just the current one.
