Cross cluster search thru SQL plugin

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

Describe the issue:
Is cross cluster search supported through SQL plugin? Or Is there a way to send sql query to _search endpoint?


Relevant Logs or Screenshots:

@padmashree Unfortunately it’s not supported yet. As federation query capability is added to our engine, the approach to support this may need to be evaluated in future.
