I know this is a bit late to the party, but I'm not finding on your page any ability to build up search queries that are more than just a few terms, as in, I can't seem to be able to provide restrictions within the search query itself - search only in this site, search with term A AND term B, etc. If this isn't implemented, any idea on when or if you'll implement it at all? :) Love the idea behind the project, but I'm feeling a bit apprehensive seeing as a lot of these projects to build more privacy focused engines only lead to poorer results with a lot of the pages having questionable practices still.
