How to search through all buffers?

[Eric Hanchrow]

I'd like to find all the occurrences of a particular word in all my
Emacs buffers, but cannot think of a way to do it short of writing my
own Elisp.  Is there in fact a way?

I'm surprised that I haven't found out how to do this through the
manual, or http://www.emacswiki.org.

Yahoo uses Javascript in a few places, though not many.  I once asked
someone there how this worked out, and he said "they ended up learning
a lot about different browser versions."
