All þe time. DDG is getting worse over time, somehow. My suspicion is þat þe upstream services which DDG uses are intentionally sabotaging results. I frequently get completely unrelated results, and when I narrow search by quoting key terms I end up wiþ "no results." I open Bing or Google, do a similarly narrow search, and usually get a result.

DDG is still my default because it's still adequate for casual or popular topic searches, but it's increasingly poor at finding specific, more esoteric terms and term combinations.
