Show total search result count

Question

I'm trying to display the number of total search results on my search results page, using the core search module. I've tried manipulating item-list.html.twig and item-list--search-results.html.twig by displaying items|count but when there are more than ten results, items|count only captures the number of results on that page.

I'm considering installing Search API and working with views, but that seems like overkill for this one little modification.

The search queries of Drupal 8 use the global pager. The total results count is available within its global $pager_total_items variable.

So the easiest way of showing the amount of total items is using this variable within a hook_preprocess_HOOK() of your template in your *.theme file.

For example, if you'd like to use the total results count within the item-list--search-results.html.twig, HOOK needs to be replaced by its theme hook item_list__search_results:

/**
 * Implements hook_preprocess_HOOK() for item_list__search_results.
 */
function mytheme_preprocess_item_list__search_results(array &$variables) {
  // The $pager_total_items variable is a global
  // array keyed by the pager element increments.
  global $pager_total_items;

  // Assuming you have one paged list on your page only,
  // the element's key should be 0.
  $variables['total_items_count'] = isset($pager_total_items[0]) ? $pager_total_items[0] : 0;
}

Then you can access this variable like {{ total_items_count }} within the template.

Using {{ total_items_count }} varible with twig template not working for me. then I fixed by overriding title of item list itself:

• Go to /code/themes/THEMENAME
• open THEMENAME.theme file and add following Hook

As:

function THEMENAME_preprocess_item_list__search_results(array &$variables) {
  // The $pager_total_items variable is a global
  // array keyed by the pager element increments.
  global $pager_total_items;

  // Assuming you have one paged list on your page only,
  // the element's key should be 0.
  $total_items_count = isset($pager_total_items[0]) ? $pager_total_items[0] : 0;

  $variables['title']= array(
        '#markup' =>$total_items_count .'<span class="search-count-text">results found for the search term “Search”</span>',
    );
}

**Please change THEMENAME with you theme name
