**My code written in nodejs**  
import elasticsearch from 'elasticsearch';  
const elasticClient = new elasticsearch.Client({  
host: es\_host  
})  
let body =   
let \_query =  
{  
"size": 1,  
"query": {  
"match": {"item\_id" : 1}  
}  
};  
body.push({index: "myindex"})  
body.push(\_query)  
let result = await elasticClient.msearch({ body: body })

**Getting Error From Elasticsearch Api**  
'{"error":{"root\_cause":[{"type":"parsing\_exception","reason":"Unknown key for a VALUE\_STRING in [index].","line":1,"col":10}],"type":"parsing\_exception","reason":"Unknown key for a VALUE\_STRING in [index].","line":1,"col":10},"status":400}',
