You meant `2.0.0` right? Not `2.2.0`? I think you are hitting this issue: [https://github.com/dadoonet/spring-elasticsearch/issues/72](https://github.com/dadoonet/spring-elasticsearch/issues/72) I need to review this proposal which will hopefully fix it: [https://github.com/dadoonet/spring-elasticsearch/pull/78](https://github.com/dadoonet/spring-elasticsearch/pull/78) This comment might help you in the meantime: [https://github.com/dadoonet/spring-elasticsearch/issues/68#issuecomment-110997891](https://github.com/dadoonet/spring-elasticsearch/issues/68#issuecomment-110997891) ---
