Provide several result pages (one for each content type)

Hi,

I find this module really great ! For a project I'm currently working on, I had to provide several links to "filter" the results for each content type on the search-results page. I was wondering if you'd be interested in adding it to the module.

My code is the following :

function custom_search_preprocess_search_results(&$variables) {
  // Get search words (minus type:node_type)
  $keys = search_get_keys();
  if (strpos($keys, 'type:') !== FALSE) {
    $keys = substr($keys, 0, strpos($keys, 'type:')-1);
  }
  // Get Custom Search authorised types
  $searchable_node_types = variable_get('custom_search_node_types', array());
  $searchable_node_types = array_keys(array_filter($searchable_node_types, 'custom_search_filter_array'));
  $node_types = db_query("SELECT type, name FROM {node_type} WHERE type IN (". db_placeholders($searchable_node_types, 'varchar') .")", $searchable_node_types);
  // Build menu
  $items = array();
  $items[] = l(variable_get('custom_search_type_selector_all', CUSTOM_SEARCH_ALL_TEXT_DEFAULT), 'search/node/'.$keys);
  while ($node_type = db_fetch_array($node_types)) {
    // FIXME : add active class when needed...
    $items[] = l($node_type['name'], 'search/node/'. $keys .' type:'.$node_type['type']);
  }
  $variables['custom_search_menu'] = theme('item_list', $items);
}

The filter_array method is :

/**
 * Function used to filter node_type array to only filter those that are configured in Custom Search Form
 */
function custom_search_filter_array($value = FALSE) {
  return $value !== 0;
}

The only thing left to do is adding

<?php print $custom_search_menu; ?>

to the search-results.tpl.php

I'm sure can integrate it better in your module, I just wanted to share what I have done. If you're interested and I make it better during the project, I'll come back and provide a patch.

Best regards
