This is the default Vortex script: texis/testdb/index.vs in your Thunderstone Texis install dir.

To run a specific Vortex script, add its path (without the Script Root) to this page's URL.
For example, to run the Vortex script mytest in your Texis Script Root dir, use the URL:
http://www.unhcr.org/cgi-bin/texis/mytest/

If you installed Webinator, to access your admin interface and search script use URLs like:
http://www.unhcr.org/cgi-bin/texis/webinator/dowalk/
http://www.unhcr.org/cgi-bin/texis/webinator/search/
