Thx! -----Ursprüngliche Nachricht----- Von: Erick Erickson [mailto:erickerick...@gmail.com] Gesendet: Mittwoch, 7. Januar 2015 17:31 An: java-user Betreff: Re: Looking for docs that have certain fields empty (an/or not set)
Should be, but it's a bit confusing because the query syntax is not pure boolean, so there's no set to take away the docs with entries in field 1, you need the match all docs bit, i.e. *:* -field1:[* TO *] (That's asterisk:asterisk -field1:[* TO *] in case the silly list interprets the asterisks as markup) There's some special magic in filter query processing to handle this case, but not in the main query parser.
