Bitbucket Data Center Elasticsearch index

[scharfs]

According to https://confluence.atlassian.com/bitbucketserver/use-an-elasticsearch-cluster-with-bitbucket-data-center-913477079.html I need to have a dedicated Elasticsearch Cluster for Bitbucket Data Center.

We already have an Elasticsearch Cluster running, so I thought lets use it.

In the Elasticsearch configuration inside Bitbucket Data Center I can only configure url, username and password.

Is there a way to configure Bitbucket to use a specific index or do I need to setup a dedicated Elasticsearch?

I also can't find a list of used indices in the documentation.

I'm also interested in setting primaries, replicas etc. in the bitbucket config
