I'll preface this by saying that I've looked at the fastsearch module and it seems to say that the search module is a requirement, that it's not installed, and the search module doesn't appear for me on the administer modules to add it - though all the search functionality is there in the site.
So I'm currently writing a customized search that will filter out search results (in this case anecdotes) depending on checkboxes. I've altered the search form to add 2 checkboxes... one to show PG-13 content, the other to show R. By default I'm looking to to show only PG rated anecdotes.
function pgsearch_form_alter($form_id, &$form) {
if ($form_id == 'search_block_form' || $form_id == 'search_theme_form' || $form_id == 'search_form') {
$options = array(
'PG13' => t('Show PG-13'),
'R' => t('Show R') );
$form['boxes'] = array(
'#title' => t('Filters'),
'#type' => 'checkboxes',
'#description' => (t('Please check to add to your search.')),
'#options' => $options,
'#weight' => 25
);
}
}
