How do you search the Usenet Archives?

I used to be able to search for my decade-old posts to Usenet Newsgroups via Google Groups but Google seems to have removed this ability (or hidden it from me beyond my capabilities to find it). I have been similarly unable to get an understanding of how theusenetarchive.com works -- I can't seem to get any search result no matter what combination of parameters I enter.



Google searching does not provide any help.



Can anyone here? :con2:
