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

To run a specific Vortex script in your web server's document tree, add its path (minus the document root) to the URL. For example, to run the Vortex script scripts/mytest in your document tree, use the URL:
/cgi-bin/texis/scripts/mytest/

If you installed Webinator, to access your search script use a URL like:
/cgi-bin/texis/webinator/search/.
