   Thanks for your request but we may not add this feature.
   Message tags is designed for message filter [Message filtering](https://partners-intl.aliyun.com/help/doc-detail/29543.htm)
   If you want to query message by index, you should use `key` but not `tag` (a message can contains multiple keys)
   ```java
   Message msg = new Message("TopicTest",
       "TagA",
       "Hello world".getBytes(RemotingHelper.DEFAULT_CHARSET));
   msg.setKeys(Arrays.asList("key1","key2"));   // you by query by both key1 and key2
   SendResult sendResult = producer.send(msg);
   ```
   
   Hope this solves your problem.
