Clearing fix version.
> Deleted documents as a Filter or top level Query
> ------------------------------------------------
>
> Key: LUCENE-1533
> URL: https://issues.apache.org/jira/browse/LUCENE-1533
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Index
> Affects Versions: 2.4
> Reporter: Jason Rutherglen
> Priority: Minor
> Original Estimate: 504h
> Remaining Estimate: 504h
>
> In exploring alternative and perhaps faster ways to implement the
> deleted documents functionality, the idea of filtering the deleted
> documents at a higher level came up. This system would save on
> checking the deleted docs BitVector of each doc read from the posting
> list by SegmentTermDocs. This is equivalent to an AND NOT deleted
> docs query.
> If the patch improves the speed of indexes with delete documents,
> many core unit tests will need to change, or alternatively the
> functionality provided by this patch can be an IndexReader option.
> I'm thinking the first implementation will be a Filter in
> IndexSearcher.
