sphinx中，直接取主键ID

sphinx.conf中 

sql_query    = \
  SELECT aid,aid AS testid, title,group_id \
  FROM documents

 

aid为主键ID，

必须AS成testid后，

再添加一个属性，sql_attr_uint   = testid

 

才可以显示成如下形式:

 

  [matches] => Array
        (
            [1] => Array
                (
                    [weight] => 1
                    [attrs] => Array
                        (
                            [testid] => 1                  ------------>显示出来了，这个问题搞了一下午，气人
                            [group_id] => 1
                        )

                )

        )
