I don't know if it supports multiple servers (it should!), but e*
( http://www.veryComputer.com/*.com/navigate/home.html ) offers a version of their
search engine for most of the major platforms (and even Linux someday
soon, they claim! joy!).
It might fill the bill. For the price (free), definitely worth a look.
I think most, if not all the major search systems are or will be selling
their engines for situations like yours.
