Another Search Oddity (this time Google Groups)

Earlier this month, I ran across some apparently unusual search results using Microsoft Live Search. I still think they were peculiar but I wasn't able to pin anything down conclusively. See the posts here and here.

Now I have something odd from Google Groups (i.e. their Usenet archive) in the form of content that used to be there but now appears to be missing. I understand that Google sometimes removes content for copyright and other reasons, but I can't imagine that's the case here. It's just an old post from the comp.os.ms-windows.apps.utilities.win95 newsgroup discussing an old DOS-based program of mine, Directory Freedom.

I was going through some old paper files and I ran across a hardcopy of an old (1996) posting that heaped (rather overly effusive) praise on my program. The hardcopy was a printout of a Google Groups search result. I can't tell the exact date, but there's a 2001 Google copyright notice on the bottom so I'd assume it's from 2001 or not much later. (A scan of the hardcopy is here.) Anyway, just for kicks, I thought I'd pull up the link and save a copy of the page. And I couldn't find it by searching Google Groups.

I'm not sure what to make of this. I first tried searching using some unique terms from the post and didn't come up with anything. Then I reverted to using the same search string as I had originally ("gordon haff") and going through all the results by hand. Still nothing. As far as I can tell, the post is just gone (or at least removed from search results).

Have I missed something obvious? Or is there some other explanation for this result?

[UPDATE- Mystery (mostly) solved thanks to Brandon who tracked down a search string that did work. (See comments.) My name is mis-spelled in the post in question. So why did it show up in my previous search? I can't say for sure but perhaps Google was just returning "looser" search results five years ago when there were a lot fewer sites and posts than there are today.]
