I was in this camp but find that the results I've gotten from DDG have been notably worse for the last year or so, to the point that I don't expect useful results to come out of it any more at this point. Even if I searched "site name" because I couldn't remember the URL was spelled "site-name.com" I've had no results coming from DDG, while Google had it as the first hit.
Have you experienced something similar? Are there techniques or workarounds I'm not aware of?
My condolences
