wait, do we have the same google tool bar?
Its not a search, its the part of the tool bar that says PageRank.
It has something to do with how many... actually I am not sure now I think of it.
But I know its not a search. What ever sight your one at the moment the toolbar says what its rank is.
And being number 1 is actually the low end. 10 is the highest. Microsoft website is a 10. Yahoo website is a 9.
