Elasticsearch Version: 6.0.0

I am currently having two indexes such as "user" and "purchase"

sample document :  
User Index:  
{  
"name": "Tamil",  
"id": "2"  
}

Purchase Index:  
{  
"product": "Apache RTR 200",  
"id": "p2",  
"userId": "2"  
}

we need the username in purchase index from user index based on the user Id.

is there any option avaibale in painless or someother ?
