Hoss Man updated LUCENE-383:
----------------------------
Attachment: TestConstantScoreRangeQuery.java
a Unit test for ConstantScoreRangeQuery ... that was easy to crank out based on
the existing BaseTestRangeFilter.
One catch is that the test currently fails: when i tried to prove that the
scores were not only constant, but also equaled the boost I couldn't get it to
work -- perhaps I have a missunderstanding of how HItCollector works, but I
thought that was the safest way to get a "raw" score.
> ConstantScoreRangeQuery - fixes "too many clauses" exception

> Key: LUCENE-383
> URL: http://issues.apache.org/jira/browse/LUCENE-383
> Project: Lucene - Java
> Type: Bug
> Components: Search
> Versions: 1.4
> Environment: Operating System: other
> Platform: Other
> Reporter: Yonik Seeley
> Assignee: Lucene Developers
> Attachments: ConstantScoreQuery.java, ConstantScoreQuery.java,
> ConstantScoreRangeQuery.java, ConstantScoreRangeQuery.java,
> TestConstantScoreRangeQuery.java
>
> ConstantScoreQuery wraps a filter (representing a set of documents) and
> returns
> a constant score for each document in the set.
> ConstantScoreRangeQuery implements a RangeQuery that works for any number of
> terms in the range. It rewrites to a ConstantScoreQuery that wraps a
> RangeFilter.
> Still needed:
> - unit tests (these classes have been tested and work fine in-house, but the
> current tests rely on too much application specific code)
> - code review of Weight() implementation (I'm unsure If I got all the score
> normalization stuff right)
> - explain() implementation
> NOTE: requires Java 1.4 for BitSet.nextSetBit()
