Erlang 错误请求：不支持具有第2个索引的ORDER BY

我需要从包含二级索引的表中获取记录。但我得到“错误请求：不支持具有二级索引的ORDER BY”。错误。我知道cassandra服务器中的CQL3不支持此功能。如何实现此功能

下面是我的表结构和索引创建和选择查询

1.要在cassandra中创建表：

    CREATE COLUMNFAMILY message_log(conversationid bigint,starttime timestamp,flag boolean,user_id text,expert_id text,conv_initiator_id text,message text,PRIMARY KEY(conversationid,starttime)) ;

2.要创建索引，请执行以下操作： 在消息日志（conv_initiator_id）上创建索引消息_log_idx_conv_initiator_id

3.要从表中获取记录，请执行以下操作： 选择会话id、用户id、专家id、消息日志中的消息，其中conv\u initiator\u id='1manoj@1921.168.1.64'AND flag=starttime ASC允许筛选的真实顺序

I get "Bad Request: ORDER BY with 2ndary indexes is not supported.", when I run 3rd query.

模块的Erlang部分是：

通过用户ID（从）->

---

你问题中的Erlang部分在哪里？
