If this is a bug, it's a pretty big one. Perhaps I have a setting that's been switched away from its default setting. But, I have partitioned data drive to which I've "relocated" or moved several of my user folders (music, video, documents folders, etc.) using the Location tab in the folder's properties. I have done this in Vista previously and in a previous build of Windows 7.
Here's the odd part. I cannot perform any searches in those folders at their new location at the root of my data partition, i.e. no search results appear for *any* searches! However, for those folders at the root of the data partition that did *not* originate from the User folder, searches work just fine.
Now, what in the world would cause this odd behavior??
