Getting the total number of results found from Apache Solr searches

On a recent Drupal project, the design for the search results page called for displaying the total number of results found in the page title: 120 results found for the term "school" I was using Apache Solr for the search solution, and to override the page title, I implement THEMENAME_preprocess_page() in template.php:


<?phpfunction MYTHEME_preprocess_page(&$vars) {
  if(arg(1) == 'apachesolr_search') {
    if (apachesolr_has_searched() && ($response = apachesolr_static_response_cache())) {
      $query = apachesolr_current_query();
      $keywords = $query->get_query_basic();
      $num_found = $response->response->numFound;
      $vars['title'] = $num_found.' results for the term "'.check_plain($keywords).'"';
    }
  }
} ?>

If you use the Context module, set up a context called "search" and use that condition instead:


<?phpfunction MYTHEME_preprocess_page(&$vars) {
  $contexts = context_active_contexts();
  if(array_key_exists('search', $contexts)) {
    if (apachesolr_has_searched() && ($response = apachesolr_static_response_cache())) {
      $query = apachesolr_current_query();
      $keywords = $query->get_query_basic();
      $num_found = $response->response->numFound;
      $vars['title'] = $num_found.' results for the term "'.check_plain($keywords).'"';
    }
  }
} ?>
