Thanks to The Register for pointing out a search-engine that’s new to me, the Russian Lukol claims to be a wholly anonymous search engine. So how is Lukol different from the non-tracking and privacy measures offered by DuckDuckGo? Lukol claims that…

“When we obtain enhanced results from Google, we tunnel your search query through our proxy servers, without exposing your search data.”

I’ve given it a quick test, and it seems to work fine and supports filetype:pdf. Basically it seems to be Google Search + URL-matched pictures + news down the side. I’m thinking Lukol might be useful for academics who want to search the Google Search index, in-depth and in very complex ways, without triggering anti-robot countermeasures from Google’s bots?
