Use Spotlight to Find Things
Spotlight is the search screen that you access by hitting the Home button when you are on the first screen of apps. It has a search field at the top.
Start typing and it begins to populate the list with things on your iPad, like apps, contacts, and appointments. To take this a step further than the regular iPad user did, go into Settings and tap on the General tab.
Hit the Home item in the fourth section. That screen lets you choose what your Home button does. If you choose Search Results at the bottom you can tell the OS what to search when typing into the Spotlight.
