Variable with min_doc_count

I’m would like create variable with elasticsearch datasource including min_doc_count:2.
Unfortunately min_doc_count is filtered out from query during execution.
My intention is create variable with only duplicate values.

It can be recreated on playground:
Variable query: {“find”:“terms”,“field”:"@hostname",“query”:"@hostname:*",“min_doc_count”:“2”,“size”:400}

Request query looks like:

It is visible that size parameter is altered but min_doc_count parameter is missing.

Can anybody help ? May I did something wrong.

Thank you in advance

min_doc_count is not supported in variable query. Please open a new feature request in Grafana’s Github repo if you want this feature and why it’s important for you.

Thank you for clear answer.
I will try open feature request.
