We're in a multi-cluster, cross cluster search configuration would love to expand our index alias use to cover indexes/patterns across multiple clusters. I.e. a single alias that covers indexes in multiple clusters.

Is this possible?

The question is can you add a CCS in to an alias? like so: curl -XPOST 'hd1delk01lx:9205/\_aliases?pretty' -H 'Content-Type: application/json' -d' { "actions" : [{ "add" : { "index" : "nyc1:bay\*", "alias" : "alias1" } }] } ' Since I am getting the error of { "error" : { "root\_cause" : [ { "type" : "index\_not\_found\_exception", …

Sounds like the current answer is no.

Thanks!
