             Summary: Add a TopDocsCollector which does not sort by score
                 Key: LUCENE-8880
                 URL: https://issues.apache.org/jira/browse/LUCENE-8880
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Atri Sharma


We assume that the user cares about the underlying hits being ordered by score. 
This Jira explores adding a collector which does not make this guarantee, thus 
not using priority queue as the collection data structure. This should help 
with large hits case, where the heap’s rebalancing can become a bottleneck
