stract.com

Stract is an open source search engine where the user has the ability to see exactly what is going on and customize almost everything about their search results. It's a search engine made for hackers and tinkerers just like ourselves. No more searches where some of the terms in the query arent used, and the engine tries to guess what you really meant. You get what you search for.

AGPLv3! Doesn't work in my outdated Safari though...
