function template_preprocess_search_theme_form(&$variables) {
  $variables['search'] = array();
  $hidden = array();

  // Provide variables named after form keys so themers can print each element independently.
  foreach (element_children($variables['form']) as $key) {

  // Hidden form elements have no value to themers. No need for separation.
  $variables['search']['hidden'] = implode($hidden);

  // Collect all form elements to make it easier to print the whole form.
  $variables['search_form'] = implode($variables['search']);
