You can have Google give you search results limited to specific countries by performing an advanced search, or you can perform a normal search and when the first results arrive, add two variables at the end of the url in your browser’s address bar.

The first variable is &lr= followed by the language you want your results to come in, and the second variable is &cr= followed by the country code, according to what country you want your results to come from.

For example, to have Google search results only from Greece and in the Greek language, add to the url:

&lr=lang_el&cr=countryGR
