Searching on Your iPhone
You can use the Spotlight Search tool to search your iPhone. There are a number of ways you can start a search:
Swipe down from the top of the screen to open the Notification Center. The Search bar is at the top of the screen. (Note that if you use this option when your phone is locked, you must unlock your phone to see all the results of the search).
Swipe to the right to open the Widgets Center. The Search bar is at the top of the screen.
On a Home screen, swipe down from the center of the screen to open just the Search too.
To perform a search, tap in the Search bar and type the search term using the onscreen keyboard. As you type, items that meet your search are shown on the list below the Search bar. When you finish typing the search term, tap Search.
The results are organized into sections, such as TOP HIT, APPLICATIONS, MAPS, MUSIC, and so on. Swipe up and down the screen to browse all of the results. To work with an item you find, such as to view a location you found, tap it; you move to a screen showing more information or into the associated app and see the search result that you tapped.
The results remain in the Spotlight Search tool as you work with them. To move back to the search results, tap the Back button in the upper-left corner of the screen or tap Search (which you see depends on the result you tapped on).
The results of the most recent search are still listed. To clear the search term, tap the Clear button (x). To close the Spotlight tool without going to one of the results, tap Cancel.
