Prioritize ES node for Kibana requests

Hello,

When I define a multiple elasticsearch hosts in config file, is it possible to prioritize one host over the others ?
Can I affect a weight in order to redistribute essentially to one specific node and send requests on other nodes only when this node is down ?

I have a Kibana instance on the same server that a node of the cluster. I want the requests would be redirected to this node prioritizely.

Thanks

For this purpose, Elasticsearch has a concept of a Coordinating Only node to handle load balancing. After setting up the nodes you only list the Coordinating Only node(s) as hosts in Kibana.
