Is there anyway to create a duplicate detection rule in one entity on two different fields? From the UI this seems not possible, but it seems like a lacking ..
For instance if you wanted to check a new contact against any email in email, email 2 or email 3 - you can only check across each of these fields for matches but you can't cross check them IE email to email 2 as an exact match.
Please let me know if there is a way to accomplish this using the OOB duplicate detection.
