Having used DDG for almost a decade now, I indeed doubt any objective research would come up showing the results are never up to par or even better than Google's (or other search engines for that matter). Of course I'm also not going to compare DDG results with others when DDG immediately finds what I need so never really checked that myself actually.. Still, no matter how much I like and promote DDG, I'm definitely not in the 'I always find what I need' camp. I don't know why but DDG is simply bad in some aspects. Sometimes it can be circumvented by altering search terms, but other times I have the impression after all those years its crawling or database is still lacking. I encounter this almost daily, most recent example: searching for 'preamp for hypex' Google and Bing (in private search windows) immediately turn up posts from audio forums I expect to have these topics. DDG just doesn't have those probably, because instead it automatically "Includes results for amplifier hypex" (which I find extremely annoying in any case, and makes no sense in this case since the word 'preamp' is key) and after forcing it to quote each term instead then it still doesn't come up with the expected results.
