How can we calculate percentage of field inside an aggregation?  
Aggregation Query  
`{ "size": 0, "aggs": { "field_1": { "terms": { "field": "field_1" }, "field_2": { "sum": { "script": "doc['field_3'].value + doc['field_4'].value" } } } } }`

Now we want to calculate percentage using something like this  
`(doc['field_4'].value/ doc['field_5'].value)*100`
