Show HN: A list of non-Google/DDG search engines, and a request for more

Mostly what the title says.

I mentioned the other day that I try to collect search engines, and there was some interest in seeing what I've found so far.

I haven't found much though, and would like to add more to this list. I have a special interest in special purpose search engines, as that seems more useful than trying to replace DDG or Google.

You can view the list here: http://a-shared-404.com/other-stuff/ , and if you have recommendations please leave a comment or email me.

I will try to have all additions, if any, added by Thursday or Friday of this week.
