I've built a (very) simple search mechanism for docnotes using coldfusion. While I use Radio to create Docnotes, I'm not running Radio on my server .. I run Coldfusion up there .. and so I can't use anything like seth dillingham's radio search engine. Coldfusion comes with the Verity search engine, which works OK. I'll try to build a template soon so that it looks like the rest of the site.
