Configuring fulltext_elasticsearch in NC

Hi friends. Would you be so kind to share the knowledge on configuring nextcloud fulltext app with elasticsearch, as well as configuration of java and elasticsearch themselves (versions of elasticsearch and java working together including).

Separately, please, share your experience on setting up elasticsearch in container, when nc is not in a container it is.

Please, also, focus on the memory and CPU limitations as well.

Thansk a lot!
