I love that you don't try to correct queries. I hate when Google auto-corrects my query and I need to click another link to get to my actual query. Thanks for that!
But in this case DDG does give Google's auto-corrected (without even telling you!) and I bet it happens to many terms as it is mostly a proxy/filter of Bing.
Edit: The same appears to be true for mbzrxpgjys and indoswiftjobinproduction
Edit 2: Hey, that's weird. Adding a comma, semicolon, period, or other symbol to the beginning or end of the query makes the gamed results show up on top at thor and www as well. Seems to work for all the terms at issue:
There were a number of bugs around the first result that this whole thing uncovered, so it could have been intermittent. Our backfill in the case of no results can vary. It shouldn't have been showing anything ever beyond the first result though.
It wasn't a misspelling though! That's the point. She is a cancer researcher and she meant that. Renal is for kidneys and Suttle is an author on various papers in the field.
Quotes provide you with exact match results. Putting quotes around an entire phrase isn't what I intend sometimes, and quoting each term in the query is just excessive. In that case, I'll just click the extra link...
A timesaver that might be useful on the edge cases is to prefix terms with a plus sign. +the +quick +brown +dog is easier to type than "the" "quick" "brown" "dog", and should have the same results.
