How do I search for all objects that are missing a given property (or
that property is empty)? The specific case is a string called "subcategory".
Catalog({'meta_type' : 'blah', 'category' : 'top', 'subcategory' :
<what???>})
I'm looking for the objects that have a category of 'top', but an empty
subcategory...
Thanks,
Kevin
