CHAPTER 13 ■ SEARCHING AND INDEXING CONTENT

// Format the search results $results[] = array(

'link' => url($legacy_url . 'note.pl', array('query' => $item->sid, 'absolute' => TRUE)),

'type' => t('Note'), 'title' => $note->title,

'date' => $note->last_modified, 'score' => $item->score,

'snippet' => search_excerpt($keys, $note->note));

}

return $results;

}

After cron has run and the information has been indexed, the technical notes will be available to search, as shown in Figure 13-7. They will be indexed inside Drupal, but legacysearch_search() will return search results that are built from (and point to) the legacy system.
