Muscat 3.6 was indeed a search engine, but a proprietary one - it's always seemed odd to me that a wrapper for it was ever included in PHP.
Muscat 3.6 was written in BCPL, which isn't exactly a mainstream language these days so the company needed a modern replacement, and OpenMuscat was written from scratch in C++, and released under the GPL. The plan was to use the engine in the company's shrink-wrap and bespoke projects, and also offer a commercial licence to the library for those not wanting to use the GPL, but the parent company went under in the dot-com crash.
Xapian (http://www.xapian.org/) is the living open source descendant of OpenMuscat, and has PHP bindings.

Apparently it was a search engine, which has now been rebranded as http://www.aprsmartlogik.com/ . There is a brief explanatory note at http://www.muscat.com/ . It looks like it may have previously had an open-source version ( http://open.muscat.com/ ).
