Usage documentation for _msearch

Siren Federate (Elasticsearch Plugin)
1

I want to run some join queries on an index using /_msearch APIs for multiple queries. There is the documentation for _msearch API but it doesn’t have usage example for it. I am using the syntax of _msearch of elasticsearch but that is also not working. I am using the below syntax

POST siren/<index_1>/_msearch
{}
{<join query>}
{"index": <index_1>}
{<join query>}

What error do you get ?
