I don't know when this has started but Photos doesn't seem to be indexing duplicates or People and Pets. I'm going through all my pics and found a bunch of duplicate looking pictures from 2014 (taken with an iPhone 5S, if that matters). In the past, it would catch very similar photos and this looks like it was from a burst set. I've also added a couple of people and dogs and it's not picking them up.
Is there a way to initiate an indexing?
