> Project: Lucene - Java

> This was reported on the userlist, in the context of range queries.
> Its also easy to make our existing tests fail with my patch on LUCENE-2751:
> {noformat}
> ant test-core -Dtestcase=TestBoolean2 -Dtestmethod=testRandomQueries
> -Dtests.seed=7679849347282878725:-903778383189134045
> {noformat}
> The fundamental problem is that MultiSearcher first rewrites against
> individual subs,
> then uses Query.combine() which simply OR's these sub-clauses.
> This is incorrect for expanded MUST_NOT queries (e.g. from wildcard), as it
> violates demorgan's law.
