It's difficult to think of a search term that will "stress test" a new search engine. I literally search Google anywhere from 20-100 times a day by using Ctrl+K in my browser. If that could be substituted by search engine X (where X, in this case, is Duck Duck Go) such that the results were much more precise, then that would be a basis for switching. It works, though, and it's built-in, so why switch? I don't feel one can get a promising measure of how good a search engine's results are with random queries, only how BAD they are (e.g. Cuil returning no results for "basic" queries).
