How to access Spotlight on iPhone
The great thing is that Spotlight has been integrated throughout the entire iPhone OS. Perhaps the easiest way to search for data is from the home page. When on your main page, swipe left to access the Spotlight search bar pictured here. You can easily swipe back to get back to you main page. Instead of swiping, you can also click the home button once to take you to spotlight and once more to take you back.
Remember, the home button from any app will take you back to the homepage. Clicking on the home button from the homepage, however, will take you to and from Spotlight.
There are other ways to access Spotlight within some of the iPhone applications. For example, in the Mail app, there is now a Spotlight search box at the top of the screen, right above your emails. This will restrict Spotlight in searching only for items in your inbox. You can also quickly customize whether you are searching for an email by the following categories: From, To, Subject, or All.
Spotlight search is also at the top of the contacts list in the Phone application, as it is in the Calendar application as well. Each of these searches its own application. Only the main page Spotlight search bar searches the entire iPhone
Having not been accustomed to searching on the iPhone, it has taken me a little while to get used to this new feature. Now that I am using it though, it has saved me a lot of time in opening applications and scrolling through pages of information. This has been a long-awaited feature, and I am glad that it is finally here.
