WordPress搜索排除某些分类

function search_filter( $query) {

        if($ruikeedu_search_key){
            $ruikeedu_search_key = str_replace("\r\n", "|", $ruikeedu_search_key);
            $BanKey = explode('|', $ruikeedu_search_key);
            $S_Key = $wp_query->query_vars;
            foreach($BanKey as $Key){
                if( stristr($S_Key['s'],$Key) != false ){
