If you go to google.com and you are not in the USA you will usually be redirected to a localised page e.g. google.es in the local language.
That's fine but for English learners its better to search in English via the English interface. Doing this will not only improve the search results (or at least return more in English) but the search suggestions (the text that appears as you type) will appear in English too.
Just look for the English link at the bottom of the page or go to google.com/ncr or www.google.co.uk/
