negative wildcard query
Say I have a document with field "f1". How can I search Documents which have not "test" in field "f"
I tried:
-f: *test*
f: -*test*
f: NOT *test*
but no luck. Using WildCardQuery class...
Any advices?
Thx
Clemens

RE: negative wildcard query
Posted by Uwe Schindler <uw...@thetaphi.de>.
Pure negative queries do not work, you have to add a MUST clause that hits
all documents, e.g. MatchAllDocsQuery:
query = new BooleanQuery();
query.add(new MatchAllDocsQuery(), Occur.MUST)
query.add(new WildcardQuery(new Term( "f", "*test*" )), Occur.MUST_NOT );

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...

Karl, I just saw, that I had a typo in my initial post. It should be:
Say I have a document with a single field "f". How can I search Documents which have not "test" in field "f"
I tried:
-f: *test*
f: -*test*
f: NOT *test*
but no luck. Using WildCardQuery class...
Any advices?
Thx

You'll also need things to exclude from, eg a MatchAllDocsQuery.
