/**
* @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()
