i like this approach as a possible use for a personal searchengine, that only has stuff that i have been looking at. for that it would be helpful to have some kind of browser extension that can autosubmit everything in my history. ideally that extension would also autoaccept every submission so that it can work fully in the background without my intervention.

also helpful would be a whilelist/blacklist feature, say, wikipedia and stackoverflow may always be autoaccepted while certain other sites may always be rejected, and the rest go through the regular review process.

then i can use that as my default search engine and branch out when i don't find what i am looking for. for that it would also be cool if there could be a way to search wiby and another search engine in paralell and display like 5 results from each.
