iOS 7 makes it very easy and fast to search the web or Wikipedia for information. Here's how you can do it.
1. Swipe down while on the iOS 7 home screen.
2. Type in your search term.
3. Scroll down to the bottom of the search results and tap on Search Web or Search Wikipedia.
4. Your search results will open in Safari.
Find yourself searching the web a lot from your iPhone and prefer to type your requests in rather than dictating them to Siri? In addition to searching through the stuff in your built-in iOS apps like Mail and Contacts, you can also use the built-in Spotlight search feature to search the web or Wikipedia directly.More at iLounge
