Definition of primary search node and secondary search node

I didn't know that there is a primary / secondary concept in Search node.

Search nodes

If I have three Search nodes, where exactly is "primary" / "secondary" information is stored? I couldn't find it in the pr_sys_statusnodes table.

@CloeW938

Pega does not directly designate any particular index node as 'master' / 'primary': that is decided by the ElasticSearch Cluster itself.

The 'master' designation may change; every index node is configured to be "master-eligible"

See: https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html for more details.
