@muzehyun This looks to be java client related functionality gap. Can you create the issue in this repo please ?

[muzehyun]

I'm still using "rest-high-level" client here in this repo. No major update on rest-high-level-client? Should I move to new Java client?

@muzehyun Yes you should. Moving this issue into opensearch-java.

@muzehyun Want to try to use the latest version of the client? Does it work?
