Dan,
I'm not sure on the Query Syntax, but if you had installed </ Plug> an
Omnidex Multiple key on this field, you could find all records where this
fields is blank using the argument "@ AND NOT 0:z@;" The "@" would qualify
every record (whether it has a value for this key or not) and the "AND NOT
0:z@" will subtract out every record for which we do have a value; leaving a
subset of records which don't have any value for this key.
Side note: Currently; QUERY only knows about Omnidex composite keys; not
about keys on actual fields...
</end Plug>
