<?PHP
   function RemoveFilter ( $attribute )
   {
      assert ( is_string($attribute) );

      foreach($this->_filters AS $key => $filter){
         if($filter['attr'] == $attribute){
            unset($this->_filters[$key]);
            break;
         }
      }
   }
?>

然后运行$SphinxClient-> RemoveFilter(‘你的过滤器’);删除过滤器.
