Yeah, but the point is, BY DEFAULT you CANNOT DO a local search!
If I'm looking for a document that *I* wrote, and is stored on *MY* computer, then if that computer is Ubuntu *by* *default* searching for it will try and find it on Amazon. NASTY!
Talk about a security risk! What if that's your doctor looking for a medical letter and using personally identifiable information along with the illness? Now Amazon know what illnesses you suffer from!
