How do I access Spotlight search in iOS 7?
Apple has removed the hidden first home screen in iOS 7. Instead of swiping to this screen for Spotlight, iOS users can search their iPhone, iPad or iPod touch from any home screen.
To reveal the Spotlight search bar, swipe down from the middle of any home screen. A text field will appear and real-time search results will be listed as you type.
To hide the Spotlight search either tap the Cancel button on the right, or swipe up from the middle of the search screen.
