Can an alias include multiple index patterns?

Hi OpenSearch folks,

Can an alias include multiple index patterns?

There’re multiple OpenSearch clusters and the remote_cluster query is configured properly. Example as below. And you can see the index pattern looks complex. I’d like to create an alias for it if possible.
Remote clusters:

  • c1-xxss
  • c2-cccs
  • c3-1snj

Index pattern
c1-xxss:filebeat-service-proxy-,c2-cccs:filebeat-service-proxy-,c3-1snj:filebeat-service-proxy-*

What’s the best practice to simplify the index pattern name?

Thanks // Hugo

Across clusters I don’t think there’s a way. An alias can be attached to as many indices as you want (not index patterns, though, but you can script that), but you’re restricted to the same cluster AFAIK.
