Honestly, I do not believe that.

You say, you perform the "same search", one time with IE and the other time with FF. IMO this is not correct.

AFAIK you are querying a *different* data center, since a search in a second browser, albeit on the same PC/IP, opens a whole new "search session" on google. Coincidentally, it just *might* be the same data center your search is performed on, but in most cases it is not.

Now, if the data centers are not synchronized (yet), you get different results ...

You would have to "take over" the session from one browser to the other to make sure you query the same data center.



I wonder - is there a way to determine which data center gets queried?
