patch applied to the current version.
> Duplicate hits and missing hits in sorted search
> ------------------------------------------------
>
> Key: LUCENE-456
> URL: http://issues.apache.org/jira/browse/LUCENE-456
> Project: Lucene - Java
> Type: Bug
> Components: Search
> Versions: 1.4
> Environment: JDK 1.4.2_06, probably OS independant, testet on Solaris 8 and
> Win2000
> Reporter: Martin Seitz
> Assignee: Yonik Seeley
> Priority: Minor
> Attachments: FieldDocSortedHitQueue_dups.txt,
> TestCustomSearcherSort_1_4_3.java, TestCustomSearcherSort_HEAD.java
>
> If using a searcher that subclasses from IndexSearcher I get different result
> sets (besides the ordering of course). The problem only occurrs if the
> searcher is wrapped by (Parallel)MultiSearcher and the index is not too
> small. The number of hits returned by un unsorted and a sorted search are
> identical but the hits are referencing different documents. A closer look at
> the result sets revealed that the sorted search returns duplicate hits.
> I created test cases for Lucene 1.4.3 as well as for the head release. The
> problem showed up for both, the number of duplicates beeing bigger for the
> head realease. The test cases are written for package
> org.apache.lucene.search. There are messages describing the problem written
> to the console. In order to see all those hints the asserts are commented
> out. So dont't be confused if junit reports no errors. (Sorry, beeing a
> novice user of the bug tracker I don't see any means to attach the test cases
> on this screen. Let's see.)
