To determine if there is data on Lucene.net

We are developing an application in the following environments:

I'd like to use Lucene.net to determine if there are any words, but now when I search for the word "foo" in the title field, it says "title:foo".

So what kind of query syntax should I use to search for title: no word (blank) and title: no word (blank) in the title field?

Selfless.

Query query = new WildcardQuery( new Term("title", "*"));

Now we know that we can search for "title: Word with (not blank)"

Sorry for the trouble.
