Does anyone know how to "correct" a category search result in photos? For instance, I searched my photos for "computer monitor" and it returned something that wasn't a monitor.
It's not intended to (and really can't) be perfect. It's a good way to find a photo you might be thinking of, but you can't really use it to find ALL photos of a certain type without missing anything.
I believe it also requires time for the differential privacy/machine learning to get better. It's all still new and in beta still (beta users only make up about 1-3% of total iOS users.) Once it's out and available for everyone and months/years pass it should get better over time.
