Display a Google Custom Search Engine (CSE) on your site.

Code

function google_cse_preprocess_item_list__search_results(&$variables) {

  // In the context of Google CSE, we rely on Google to render the content.
  // Therefore, we do not want to use Drupal's default list
  // (see Drupal\search\Controller\SearchController::view()).
  // The simplest way to achieve this in a Drupal context is to
  // unset the "items" sent to the list template and render the
  // Google CSE results as the 'empty' value.
  if (isset($variables['items'][0]['value'])) {
    if ($variables['items'][0]['value']['#theme'] == "google_cse_results") {

      unset($variables['empty']['attributes']);
      unset($variables['items']);
