I want to present a repeating group with records that have not changed since they were added (along with some other criteria.)
Essentially, I want the criterion to be Modified Date <> the record’s Created Date. Unfortunately, the list of available options doesn’t seem to provide any fields from the data type being searched.
Another option is to have a yes/no field under the Thing called “updated” or something and any workflow that makes a change would also set this value to “yes.” That way you can leverage that field on the server side (and not in an advanced field)… Search for Things where Updated = no.
