I tried this....

In includes\modules\pages\advanced_search_results\header_php.php I removed the following in red.

$where_str = $db->bindVars($where_str, ':keywords', $search_keywords[$i], 'noquotestring');
// search meta tags
$where_str .= " OR (mtpd.metatags_keywords
LIKE '%:keywords%'
AND mtpd.metatags_keywords !='')";

$where_str = $db->bindVars($where_str, ':keywords', $search_keywords[$i], 'noquotestring');

$where_str .= " OR (mtpd.metatags_description
LIKE '%:keywords%'
AND mtpd.metatags_description !='')";
$where_str = $db->bindVars($where_str, ':keywords', $search_keywords[$i], 'noquotestring');
