Subject AW: negative wildcard query
Date Thu, 30 Jun 2011 07:44:14 GMT
My testcase/context:

query = new BooleanQuery();
query.add( new WildcardQuery( new Term( "f", "*test*" ) ), Occur.MUST_NOT );
filter = new QueryWrapperFilter( query );
result = indexSearcher.search( new WildcardQuery( new Term( "description", "*happy*" ) ),
filter, 10 );

The filter never ever lets any documents through...when calling

result = indexSearcher.search( new WildcardQuery( new Term( "description", "*happy*" ) ),
10 );

I have hits...
