Subject: 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.

Best,
Erick
