After using user\_agent processor, I am getting the results somewhat like this:  
"user\_agent" : {  
"patch" : "1",  
"major" : "5",  
"minor" : "1",  
"os" : "Android 5.1.1",  
"os\_minor" : "1",  
"os\_major" : "5",  
"name" : "Android",  
"os\_name" : "Android",  
"device" : "AFTT"  
}

I want the fields inside user\_agent to be split and parsed so that the JSON document looks like this  
"user\_agent" : {  
"patch" : "1",  
"major" : "5",  
"minor" : "1",  
"os" : "Android 5.1.1",  
"os\_minor" : "1",  
"os\_major" : "5",  
"name" : "Android",  
"os\_name" : "Android",  
"device" : "AFTT"  
},  
"patch" : "1",  
"major" : "5",  
"minor" : "1",  
"os" : "Android 5.1.1",  
"os\_minor" : "1",  
"os\_major" : "5",  
"name" : "Android",  
"os\_name" : "Android",  
"device" : "AFTT"

You can use the `set` processor to copy every single field you want to another destination. See [https://www.elastic.co/guide/en/elasticsearch/reference/6.6/set-processor.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.6/set-processor.html)
