Hey guys,

is it possible to make some conditions in the JSON Input/Aggregations.  
For example:

> ```
> "aggs": {
> "calculation": {
> "sum": {          
> "script": if (doc['Field1'].value - doc['Field2'].value > 0) { ... }
> }
> }
> }
> 
> ```

Thanks in advance.. 🙂

I may be misunderstanding what you're trying to do, but it looks like what you need is a [scripted field](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html)
