Do you need a paid x-pack license to run cross cluster search? Or is it possible to use this feature on the free license?
The Elasticsearch documentation on cross cluster search and security indicates that to do cross cluster searching you need to:
Enable the Elasticsearch security features on every node in each connected cluster. ...
xpack.security.enabled
See Cross cluster search and security | Elasticsearch Guide [6.7] | Elastic.
X-pack, in turn, requires a paid license. Accordingly, it seems that you need a paid license to do cross cluster searching. Am I reading this correctly? Is cross cluster searching a feature that is unavailable on the free version?
