Lucene.net is not returing any hits back

See more:

C#

The idex is created and its able to update. In this code the query is getting passed as well.

hits = searcher.Search(query, new Sort()); 

Following is the MultiFieldQueryParser.

MultiFieldQueryParser qp = new MultiFieldQueryParser(fields, new StandardAnalyzer());

But there is no hits coming back. Have no clue where the issue is.. Using C# and I upgraded to .Net 4.0 at the same time and thought it might be a permissions issue on the index folder.

I granted permissions to ASP.Net machine account and IIS_WPG and then everyone.

The web is running in trust = Full and the appropriate projects allow unsafe code (a previous lucene bug).

Any help would be appreciated.
