/**

 * @file

 * Displays the search form block.

 *

 * Available variables:

 * - $search_form: The complete search form ready for print.

 * - $search: Associative array of search elements. Can be used to print each

 *   form element separately.

 *

 * Default elements within $search:

 * - $search['search_block_form']: Text input area wrapped in a div.

 * - $search['actions']: Rendered form buttons.

 * - $search['hidden']: Hidden form elements. Used to validate forms when

 *   submitted.

 *

 * Modules can add to the search form, so it is recommended to check for their

 * existence before printing. The default keys will always exist. To check for

 * a module-provided field, use code like this:

 * @code

 *   <?php if (isset($search['extra_field'])): ?>

 *     <div class="extra-field">

 *       <?php print $search['extra_field']; ?>

 *     </div>

 *   <?php endif; ?>

 * @endcode

 *

 * @see template_preprocess_search_block_form()

 */
