Search in Photos on iPad
When you tap Search in the Photos app , you see suggestions for people, places, and photo categories to help you find what you’re looking for, or rediscover a moment you forgot about. You can also type a keyword into the search field—for example, a person’s name, date, or location—to help you find a specific photo.
Tip: You can also find photos and videos in your Photos library when you Use iPad to search.

Swipe from the left edge of the screen or tap to show the sidebar, then tap Search. View photos in the suggested categories, or use the search field at the top of the screen to search by the following:
Date (month or year)
Place (city or state)
Business names (museums or restaurants, for example)
Category (beach or sunset, for example)
Events (sports games or concerts, for example)
Person (Lia or Gordon, for example)
Caption (see See photo and video information)
Looking for something more specific? Refine your search with multiple keywords—simply keep adding keywords until you find the right photo. Search also suggests keywords to add to your search.
