业务需要，laravel本身的方法 很难拼接性能比较好的sql，所以需要使用原生的sql,但是又需要laravel原来的分页

如下我的sql是这样的：

SELECT  *
 FROM `user_familyer`
   INNER JOIN(
               SELECT `uid`
               FROM `user_sign`
               WHERE `doctoruid` IN (SELECT `doctoruid` FROM `doctor_user` WHERE `hospital_id`= 32693)
                     AND `type`= 0) AS `join_user` ON `user_familyer`.`anhao_uid`= join_user.uid
 WHERE `gender`= 1
       AND realname= '程文福'
UNION
  SELECT *
  FROM `user_familyer`
    INNER JOIN(
                SELECT `uid`
                FROM `user_sign`
                WHERE `doctoruid` IN(SELECT `doctoruid` FROM `doctor_user` WHERE `hospital_id`= 32693)
                      AND `type`= 1) AS `join_family` ON `user_familyer`.`fid`= join_family.uid
  WHERE `gender`= 1
        AND realname= '程文福'
ORDER BY `sort` DESC LIMIT 10 OFFSET 0;

在laravel中 我该如何去处理这条sql，然后才能使用到分页！
