I have actually been using ddg for a long time but lately I have some things that I know exist which I access routinely and I just use search to get there for convenience because the site (a wiki) does not have the short/pretty url option enabled so the urls are all inconvenient.
When I search for it lately (several months at least), by it's exact, correct, unique name, ddg gives me everything in the world BUT the actual site. It gives me pages and pages of links to a mail list archive, admittedly from the same domain, and other random links that are either simply unrelated and wrong, or some that include mentions so they are relevant but should appear far down the list.
It's ridiculous.
Google produces links to the site top front center, as well as the indirect mentions further down.
It's a small community so I'm afraid to slashdot the guy but really a story like this is kind of dry without the real example, and maybe an ordinary HN entry is not so bad.
Search "bitchin100 rex" or "bitchin100 tpdd" or even just the plain exact unadulterated domain "bitchin100.com" in google, then the same thing in ddg. I don't even need to provide the correct results here for reference. the google ones will be correct or at least reasonable, as in on the first screen if not the very first non-ad result.
I'd be curious if using ddg anyone else in gets anything but a never ending scroll of Narkive links. To be fair, the mail list is also from the bitchin100.com domain, so those results are not wrong in that they should be there also, but the better-matching results are not only not first, they're not even there at all no matter how many "more" you load.
Could it be the word bitch in the name?
F-ing Microsoft, it's probably that.
