Elasticsearch 2.2客户端库可以与旧版本的Elasticsearch 1.3一起使用吗

Question

A feature in my project is already using 1.3 of elasticsearch and for new feature the plan is to use ES 2.2 also it is for some reasons that I cannot upgrade existing ES 1.3 to ES 2.2

Can one single version of elasticsearch client library (preferably 2.2) work with both versions of ES 1.3 and ES 2.2?

I know ES has changed a lot of their APIs from 2.0 but curious to know if someone has tried this path.

The Java client must be from the same major version of Elasticsearch as the nodes; otherwise, they may not be able to understand each other. https://www.elastic.co/guide/en/elasticsearch/guide/current/_talking_to_elasticsearch.html
