Remove Priority-Queue size trap in MultiTermQuery.TopTermsBooleanQueryRewrite
-----------------------------------------------------------------------------
Key: LUCENE-2687
URL: https://issues.apache.org/jira/browse/LUCENE-2687
Project: Lucene - Java
Issue Type: Improvement
Components: Search
Affects Versions: 3.1, 4.0
Reporter: Robert Muir
Priority: Minor
Fix For: 3.1, 4.0
These APIs are new in 3.x, so we can do this with no backwards-compatibility
issue:
Before 3.1, FuzzyQuery had its own internal rewrite method.
We exposed this in 3.x as TopTermsBooleanQueryRewrite, and then as subclasses
for Scoring and Boost-only variants.
The problem I have is that the PQ has a default (large) size of
Integer.MAX_VALUE... of course its later limited by
the value of BooleanQuery's maxClauseCount, but I think this is a trap.
Instead its better to simply remove these defaults and force the user to
provide a default (reasonable) size.
