I use google mostly for "How to do x in y framework", and I can get a good response 75% of the time, and that goes up to about 85% with some better phrasing. I tried ddg for a week, but I used g! so much that I felt a bit silly.

I've found that you can get that extra 10% of relevance by including the year in your query.
