If you are refering to QueryParser, and if you mean that you want =20
Lucene to *find everything* when you actually say *search for =20
nothing*, you could easily extend current Queryparser to suit your =20
needs:

public class MyQueryParser extends QueryParser
{
     public MyQueryParser(String f, Analyzer a)
     {
         super(f, a);
     }

     public Query parse(String query) throws ParseException
     {
         if (null =3D=3D query || query.trim().length() =3D=3D 0)
         {
             return new MatchAllDocsQuery();
         }
         return super.parse(query);
     }
}

Ronnie
