You can try to use a range query something like test:[null TO "zzzzzzzzzzzzzzzz"] Please note that you might get TooManyBooleanClause Exception, if you have too many of them.
The other thing you can use is with the operator NOT. For all the Empty fields you can fill them with a string lest say "empty" and then query for -test:empty Aviran -----Original Message----- From: MATL (Mats Lindberg) [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 06, 2004 16:27 PM To: Lucene Users List Subject: how to find field that has any value Hello i have a probably simple question for some of you. Since lucene does not allow a query to start with a wild card (* or ?) how would i find all documents in lets say field test that has something in that field, or is not empty. my first thought would be to do something like this. test:________ (cause the value ______ isn't very likely to be present) test:* (would be the correct way, i guess, but lucene doesn't allow that) does anyone have a greater idea.
