Polish guy living in Chile, using DDG as a main search for something like 2 years ago now. on the occasion (once every week maybe?) I switch to Google (!g + search) if DDG doesn't give me good result, but with Google recently almost every time I have to switch to verbatim mode as normal one returns garbage...
rest od the searches are rather ok, but I'm mostly searching in English and Spanish. in the latter case I sometimes have to force local results (toggle in the search pageof DDG) as it returns results from different Latin countries.
