I trying to loop thrus a single index (eg: userprofiles) and update the single field (eg: user\_type) if the userprofiles.NAME is exist in other index (eg: badlistedusers)

Can "\_update\_by\_query" API do that?

**userprofiles mapping**

"mappings" : {  
"doc": {  
"properties" : {  
"NAME" : { "type" : "text" },  
"USER\_TYPE" : { "type" : "text" }  
}  
}  
}

**badlistedusers mapping**

"mappings" : {  
"doc": {  
"properties" : {  
"NAME" : { "type" : "text" }  
}  
}  
}
