Theres alot of search engines out there, one of which is "MetaCrawler".
I was recently told about a link that allows you to see peoples search querys live,
http://www.metaspy.com/_1_283IT2507232VY__info.metac.spy/metaspy/unfiltered.htm I searched the MetaCrawler site for awhile and didn't find any links to the above page. The page shows all the recent searches done by people, I'm unsure of the legality involved in this, but I assume the site has a colorfull privacy policy.
Anyway, after about three minutes of watching peoples searches, you start to see some interesting stuff, such as people searching for warez, or people looking for a weather forecast of Russia.
Its very interesting to watch,
