Searching Apple’s Stores With Google
iTunes used to have a Power Search feature, but it has been removed from the iTunes app (though you can still access it this way). Power searching is really useful when you want to home in on something in the iTunes Store, App Store, or Mac App Store.
In the absence of a real power search, you can search another way: with Google. A Google search works because Apple has Web pages for all its iTunes Store content. With Google, you can search for more specific keywords and use quotes to search for specific phrases.
