How to fetch data from multiple hostnames in es

hey all iam new to elk , iam trying to get all the hosts in the Elasticsearch db , i tried using a wildcard and

"wild_card": "hosts",
"query": {
"host.keyword": "test*",
"severity.keyword": "err"

consider there are multiple hosts like test1,test2,test3 i want to all them to be listed in a query , can someone help me with this


what do you mean with that? Do you want to list the nodes? If so:

GET _cat/nodes

Also: Cluster APIs | Elasticsearch Guide [8.3] | Elastic could help.
