But it does come in handy, though it is a little frightening.
When I do a search I usually don't have to select "page from Australia" especially if it a subject that I have looked at before. But what really surprised me, I was searching for public records of something, not only did it select all Australian, but after the first few, it asked if I meant NSW (state), which is the state where I live.
Very handy yes, but definitely a little scarey.
