I have this question: Suppose I am in Brazil, then I type www.google.co.uk in the address bar of the Internet browser and I make a search in English. Am I going to get the same results than if I made the search in England?
I don't think the results are the same across the board, you will get different results based on which google server you are querying.
if u go to .co.uk then u will get the same results than in england m8, i do this everyday to check my stats
Yah you will get roughly the same results as if you were in that location, it will vary depending on which server you query.
