/**
 * @file search-results.tpl.php
 * Default theme implementation for displaying search results.

 * the child template are dependant to one another sharing the markup for
 * definition lists.
 *
 * Note that modules may implement their own search type and theme function
 * completely bypassing this template.
 *
 * Available variables:
 * - $search_results: All results as it is rendered through
 *   search-result.tpl.php
 * - $type: The type of search, e.g., "node" or "user".
