At indexing time, SortingMergePolicy serializes the sort order that
has been used into the merged segment. At search time, the collector
checks for this information: either the sort order matches and ESTC
will early-terminate collection on this segment, or the sort order is
not specified in the segment or doesn't match, and all documents that
match the query will be collected as usual. This makes sure that all
matches that might be competitive are collected.
