I have following Json records in Elasticsearch:  
{  
"endpoint": "bulk",  
"application": "Interface",  
**"message": "Request finished",**  
"@version": "1",  
**"requestId": 18714,**  
"@timestamp": "2016-01-29T20:22:43.684Z",  
},  
"fields": {  
"@timestamp": [  
1454098963684  
]  
}  
}

{  
"endpoint": "bulk",  
"application": "Interface",  
**"message": "Issuing Request",**  
"@version": "1",  
**"requestId": 18714,**  
"@timestamp": "2016-01-29T20:22:43.411Z",  
},  
"fields": {  
"@timestamp": [  
1454098963411  
]  
}  
}

How should i write the query which can subtract the timestamps of "requestID=x issuing request" to "requestID=x request finished"?
