Michael McCandless commented on LUCENE-4366:
--------------------------------------------
The patch specializes the [private] collector BS uses to add docs to the bucket
list, eg the first clause need not check if the bucket is stale because it
always is. It sorts the clauses first by prohibited clauses and second by
smallest firstDocId (proxy for highest docFreq). It uses an int[] instead of
linked list to track live buckets ...
