Faceted search over a network connected was demonstrated in a video education series (some sort of HCI distance education class) hosted by Ben Schneiderman of the university of maryland in the fall of 1992. I don't have a link or more concrete reference to give you nor any idea if that would help in this specific case.

We were using faceted search on the IBM Corporate web site in the 1998-1999 timeframe, I believe in the IBM PC “shop” site, however I no longer have any of the relevant information/documentation (IBM might).

I think what I was thinking of was "Dynamic Queries: database searching by direct manipulation" which is linked off here: http://www.cs.umd.edu/hcil/pubs/video92.shtml. That may not be as applicable as I thought it was.
