PHP MYSQL WHERE AND跟OR

想請問一下該怎麼下where條件

WHERE `status` = '已完成' AND `type` = ''AND `phone` LIKE '%{$user}%'OR `phone2` LIKE '%{$user}%'OR `address` LIKE '%{$user}%'OR `name` LIKE '%{$user}%'OR `email` LIKE '%{$user}%'ORDER BY `buytime` DESC

條件是"status一定要是已完成 然後type一定要是空"
然後其他任一個有符合的都可以

我這樣子做會變成status不是已完成 type不是空的也會被搜尋出來
