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

Say I wanted to find documents which have no content in "field1" (or dosuments
that have no field 'field1'), wouldn't that be the following query?
-field1:[* TO *]
