Adrien Grand created LUCENE-4925:
------------------------------------
Summary: IndexSearcher.search is broken when
IndexSearcher.executor != null and the sort contains SortField.FIELD_SCORE
Key: LUCENE-4925
URL: https://issues.apache.org/jira/browse/LUCENE-4925
Project: Lucene - Core
Issue Type: Bug
Affects Versions: 4.2.1
Reporter: Adrien Grand
Assignee: Adrien Grand
Fix For: 4.3
When executor != null, IndexSearcher performs two passes to compute the top
docs. This doesn't work when the sort contains SortField.FIELD_SCORE because
the second pass doesn't have access to scores computed in the first pass.
Since search(...) doesn't compute scores when there is a sort, they are all
Float.NaN.
