But that is to avoid indexing, isn't it?

If so, I'll still have the problem because my searches uses the
wildcard "*" at the end.

Or does it filter also the query when it parses:

            var parser = new
MultiFieldQueryParser(Lucene.Net.Util.Version.LUCENE_30,
fieldsToSearch, _analyzer);

            keyword = keyword.Replace("-", " ");

            keyword = QueryParser.Escape(keyword);

            var main = parser.Parse(string.Join(" ",
keyword.Trim().Split(' ').Where(x =>
!string.IsNullOrEmpty(x)).Select(x => x.Trim() == "*" ? x.Trim() :
x.Trim() + "*")));
