Subject [jira] Commented: (LUCENE-383) ConstantScoreRangeQuery - fixes "too many clauses" exception
Date Wed, 26 Oct 2005 21:23:55 GMT
    [ http://issues.apache.org/jira/browse/LUCENE-383?page=comments#action_12356014 ] 

Doug Cutting commented on LUCENE-383:
-------------------------------------

I like this patch.  It would be nice to have a unit test, and we need to agree that Lucene
1.9 will require java 1.4 (which seems reasonable to me) before we commit it.

Once this is committed, should we consider changing the query parser to use ConstantScoreRangeQuery
for range queries?  That alone would probably solve the majority of too-many-clauses problems.

> 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()
