The following is a function from zend_mail_protocol_imap. i read that to search emails, I would want to override it using zend_mail_storage_imap (which is what I'm using now to grab email from gmail). I copy and pasted the following function into zend_mail_storage_imap, but I'm having issues with the params. I can't find documentation on what to use for the array $params. I initially thought it was the search term before reading it more thoroughly. I'm out of ideas. Here's the function...

/**
 * do a search request
 *
 * This method is currently marked as internal as the API might change and is not
 * safe if you don't take precautions.
 *
 * @internal
 * @return array message ids
 */
public function search(array $params)
{                                                                                    
    $response = $this->requestAndResponse('SEARCH', $params);
    if (!$response) {
        return $response;
    }

    foreach ($response as $ids) {
        if ($ids[0] == 'SEARCH') {
            array_shift($ids);
            return $ids;
        }
    }
    return array();
}

Initially I thought this would do the trick...

$storage = new Zend_Mail_Storage_Imap($imap);

$searchresults = $storage->search('search term');   

But nope, I need to send the info in an array. Any ideas?
