Restrict search queries to hot nodes

Hi,

If for example, I configure an index policy to send an index to a cold Elasticsearch node. How to ensure that search queries on Elasticsearch only process hot nodes and not cold ones because researching cold nodes will be costly? Can this be done with Rollups? If so, how ?

Thanks in advance

Which action are you referring to - Policies - Open Distro for Elasticsearch Documentation?
