Subject Re: InverseWildcardQuery
Date Fri, 30 Jul 2010 15:19:24 GMT
I think you're suggesting, for example, "*:* AND -myfield:foo*".

If my document contains "myfield:foobar" and "myfield:dog", the document would 
be thrown out because of the first field. I want to keep the document because 
the second field does not match.

Related, is there a way to use wildcards to match the beginning of the field?

org.apache.lucene.queryParser.ParseException: Cannot parse '*:* AND 
-myfield:*foo*': '*' or '?' not allowed as first character in WildcardQuery

I can't get my head round exactly what you want, but a standard lucene
technique is a BooleanQuery holding a MatchAllDocsQuery and a second
query, can be anything, having Occur.MUST_NOT.  I guess that is a way
of inverting the second query.
