I am using 6.4.1 APIs and need to know how does one 'delete by query' in this version. I have initialized my HighLevelRestClient using two coordinating nodes?
I don't want to use REST call, because i want to connect to my two coordinating nodes and i cannot do that in a REST call.
I understand that it is available on master or on later versions. But i need a way in 6.4.1.
