The Thunderstone Search Appliance is a web walking and indexing device
that allows a web site
administrator to provide a high quality retrieval interface to
collections of HTML and other documents. It is an application of Texis
and is written in Texis's Web Script language named Vortex.
It consists primarily of the Texis binary program and two Vortex
scripts that are run by the Texis CGI program on
the Search Appliance
and are accessed from a web browser.
One script provides the administrative interface, another provides the
site walker and indexer, and the third provides the search function
that end users see.
