This may have been covered already, but I didn't find it in the search. That said, if this is a duplicate, my apologies.
I'm trying to filter out specific word combinations, but ignore instances where those words appear individually or in other pairs. Like so:
Juan Valdez - This would be marked read or deleted.
Juan - Ignored
Valdez - Ignored
Juan Pablo - Ignored
Carlos Valdez - Ignored
Valdez University defeats Juan University in baseball - Ignored
Sorry for the lame examples, but they get the point across. So, is this possible? If so, I'm obviously not doing something correctly. Any assistance would be appreciated.
