For a relatively small DB the results I got were pretty good. Some of the warhorses were missing but everyone displays them because they are copying the Google serps as much as they can. mojeek is ranking for itself which brings up interesting stuff that are just as relevant as the warhorses.
This all makes me wonder if good metasearch engines might make a comeback? Part of what killed metasearch was all the engines and directories died so it was just Google and Bing and engines using Bing, not very interesting. But with Gigablast (open source) and mojeek, Yandex and others combined with Bing maybe it's time to revisit the viability of metasearch. (DDG is really just a blended metasearch anyway.)
In this thread:
http://th3core.com/talk/water-coolerextra/new-sighting-'duck-duck'-as-a-verb/ we talk about
searx.me an open source meta search engine that is pretty good and hackable. Something like that might be interesting. I wish I had the knowledge to install and maintain the script because I'd put it on a server, I guess for no other reason than to say I was back into search again.
Or maybe bribe littleman to put a searx instance up on th3core so we don't get tracked by The Man.
