I am getting below output after apply aggregate but i have perform subtraction on "key": "in-completed","doc\_count": 4 and "key": "completed", "doc\_count": 2  
expected  
output - [in-completed][doc\_count] - [completed][doc\_count]

Please tell me if its possible in elastic search script because subtraction count need display in kibana dashboard
