Search in Photos on iPad
When you tap Search in the Photos app , you see suggestions for moments, people, places, and categories to help you find what you’re looking for, or rediscover an event 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 any of 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)
A person identified in your People album (see Find and identify people in Photos)
Text (an email address or phone number, for example)
Caption (see See photo and video information)
The person who added the photo to the library (see Set up or join an iCloud Shared Photo Library in Photos on iPad)
Tip: 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.
