If DDG results are unsatisfactory, you can add a `!s' to your query and it will take you to the results of startpage.com
I experimented with DDG, but startpage is giving me better results at this time - especially if you are searching for something more local. So I set startpage.com as default search engine on all of my devices. I may try it again later...
Yeah, I switched to DDG, but it didn't give me satisfactory results, particularly for debugging searches. Moved to startpage, and am a happy user since two weeks now.
