Hello, I want to subtract the sum of two metrics in Kibana.  
C = A + B  
If I have metric C which is the sum of metric A and metric B.  
I created metric C with search query "id1:100 && id2:93" and give the total of 14,000,000  
I created metric A with search query "id1:200 && id2:93" and give the total of 1,000,000  
How do I produce metric B, which is C - A, in Kibana metric visualization (give total 13,000,000) ?  
What operator should I use specifically?

You can't currently do this, pipeline aggs in Elasticsearch 2.0 will allow you though.
