Should this be added? I say it's to hard and not simple. Half the time people don't know how to use them anyways... :-)
Seriously, technically its possible... but I'm still playing with the idea of doing it external to the wiki via htdig or something. 'course, that means a cronjob has to be run to index it and stuff...
Hmm, it may make most sense to just build it into the MiniWiki, and just list all files that contain the specified string... --Wim
