Developer's Quarterdeck Log

I have noticed something kind of strange, I usually find the information I am looking for faster via Google than I can with using the "man" command right on my own machine.  Google tries to guess what I am looking for by the domain, location, and other secret sauce components to try to customize a search results which work pretty good most of the time.  I wonder if the shell should try the same thing?  After all, most shells keep a history of commands so maybe it could use that information to help rank a man -k search?  Just a thought.  Probably just too much work, why reinvent the wheel anyway?
