/*
 * Demo for LibX's custom catalog functionality.
 *
 * This script is read whenever the user opens a new window.
 * It is recommended that you install it on a machine that can
 * handle this load, such as googlepages.com
 *
 * The entire JavaScript content is evaluated.  This evaluation
 * does not happen in a sandbox.  Therefore, be careful to not
 * configure your edition to draw catalogs from people you do not
 * trust.
 *
 * The object 'thisCatalog' is defined to refer to the catalog
 * instance being added. You must implement makeSearch and 
 * makeAdvancedSearch.
 * The properties url, name, and options are already set from 
 * your configuration file, and so are param0 to param19 if 
 * configured.
 *
 * Follow the examples in:
 * http://libx.org/libx/src/base/chrome/libx/content/libx/catalogs/
 * See http://libx.org/libx/src/base/documentation.txt for the
 * meaning of the search type field.
