I neglected to mention that I'm using Atomz for the search engine here. As a free (limited) service, they do some very slick search stuff, and because they provide contextual results (showin the words they found, in context), they are ideal here. I heartily recommend them.

UPDATE (24 Jul 07): No longer using Atomz, but the internal MT search system (possibly to be someday updated to MT FastSearch, or even possibly MTGoogle). Atomz (now part of WebSideStory) has done well by me, so I still encourage you to consider it in your own site design, even if it doesn't fit mine any more.
