Find Everything With Search
Spotlight Search, also known as Search on iPhone, is the most powerful tool you need to learn. This feature will help you find almost much anything you have stored on your iPhone.
You can search for apps, documents, and even do basic calculations or currency and unit conversions. You can even search for text that’s in your photos, and your iPhone will search for the photo you’re looking for. If it can’t find anything on your iPhone, it’ll suggest taking your search to the web.
To use Spotlight Search, all you need to do is tap the Search button on your home screen. It’s right above the app’s dock near the bottom of your screen. You can also pull it down with your finger on your Home Screen to make it pop up.
