If your meaning the content search, it's in the library. Click the library, there will be 3 tabs .. Library, Search & Favorites. To Search online, you type in what you want to search for, then click the little magnifying glass in the cloud (Left of the Sort By: .. selector). Then it will search online, if the cloud isn't toggled on (yellow) it will search your local libraries. I can live with it there, as it is totally unobtrusive, when it was a tab I would accidentally keep clicking on it.

Consider me insane if you wish, but is your reality any better?
