【異常】關於使用ES的RestHighLevel JavaAPI執行search操作時，參數的問題

問題描述：

在使用ES的JavaRest API 的RestHighLevelClient，執行searchRequest操作時，出現部分請求參數不能識別的情況，如下：

contains unrecognized parameters: [batched_reduce_size], [typed_keys]]

ElasticsearchStatusException[Elasticsearch exception [type=illegal_argument_exception, reason=request [/finance.qyxx_basic/qyxx_basic/_search] contains unrecognized parameters: [batched_reduce_size], [typed_keys]]

其實問題很讓人蛋疼，ES的REST JavaAPI中高級API，是在5.6之後的版本採用的，而我的ES服務版本正好5.3的，導致5.3就不能識別5.6提供的參數。
