Tuned better for pd-* mailing lists and still excludes ads: http://google.com/search?q=+++++++pd-list+OR+pd-ot+OR+pd-dev+site%3Aiem.kug....
the best search possibility is always your own hard drive / mail client ... especially if you only have a dialup connection...
i'm not sure, who is maintaining the mailinglist (IOhannes???), but it would be pretty cool if you could provide an mbox file of the old archives for download ...
cheers...
