Как сделать поиск похожих новостей в админки только по заголовку со 100% совпадением?

$db->query( "SELECT id, title, date, category, alt_name, MATCH (title, short_story, full_story, xfields) AGAINST ('$title') as score FROM " . PREFIX . "_post WHERE MATCH (title, short_story, full_story, xfields) AGAINST ('$title') AND approve='1'" . $where . " ORDER BY score DESC, date DESC LIMIT 5" );

$db->query( "SELECT id, title, date, category, alt_name FROM " . PREFIX . "_post WHERE `title` = '" . $title . "' AND approve='1'" . $where . " ORDER BY date DESC LIMIT 5" );
