Let's say I have photos with the following entries for "Persons Shown":
#1: Fred
#2: Fred, Barney
#3: Wilma, Betty, Pebbles
#4; Fred
#5: Fred, Dino, Barney
Is it possible to search for the photos that have Fred, and only Fred, in the "Persons Shown"? In other words, only return photos #1 and #4.
I've tried this but it doesn't work: pershown is fred
