Search for photos on iPod touch
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.
Tap Search, then tap 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, 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.
