Find properties that do not exist

[az_ltr]

Is there a direct way to search for properties that do not exist?  I know you can search for the all the elements and then add the property to the result list and parse from there but seems like there should be a conditional that is DNE so you can quickly find elements that do not contain a property.

Hi az,

I'm afraid that query option does not exist for the DataFinder.  You only option is to query all the possible files that might or might not have that property and send that to Results1, then query all the possible files that do have that property and send it to Results2, then use the query set functions to remove Results2 from Results1.  If Results1 is to big a result set for this approach to be practical, then I'm afraid your stuck.
