The problem DDG has is not understanding the search terms. eg "usb 3 voltage" will get you lots of results as though you had left out one or two of the words (there are far more pages about "usb voltage" than "usb 3 voltage"). You know the 3 is critical, but they don't. A general rule of thumb is that 3 or more words in your DDG search dramatically worsens the results. (Amazon search is even worse where two words begins the spiral of spectacularly bad results.) That said DDG often does get reasonable results. And if you don't like them, just add in !g to see what google gets. (Conceptually I like to give DDG first crack at a search, and then fallback to google if DDG didn't do well.) What I have noticed is google's results are getting worse, as sites are getting better at gaming google.
