This is what we do on a Drupal 5 site. Should work more or less the same on D6 as well.

In template.php, we include an inc file that handles the XML from the external site, and then we add "sponsored results". Like so:


function phptemplate_search_page($results, $type) {
  $enable_external = FALSE;

  $external = path_to_theme() . '/something_search.inc';
  if (file_exists($external)) {
    include_once($external);
    if (function_exists('external_search')) {
      $enable_external = TRUE;

      // This is the search term. Remove + in case it is a multiword search
      //$key = trim(preg_replace('/\+/i', ' ', arg(2)));
      $key = arg(2);

      // run the function to get results
      $external_results = external_search($key);

      list($jr_top, $jr_bottom, $jr_sidebar) = $external_results;
    }
  }

  $output = '<dl class="search-results">';

  if ($enable_external) $output .= '<div class="sponsored">' . $jr_top . '</div>';

  foreach ($results as $entry) {
    $output .= theme('search_item', $entry, $type);
  }

  if ($enable_external) $output .= '<div class="sponsored">' . $jr_bottom . '</div>';

  $output .= '</dl>';
  $output .= theme('pager', NULL, 10, 0);

  return $output;
}

Hello,

I like to add some search result from a different site to drupal. I like to show the search results mixed in the other and drupal site. I try to use mnogosearch to index the other site, but I can not insert the results to the drupal results. How can I make it?
