Hi guys,

I've a sample dataset with 3 columns (ID, ACTION and AMOUNT):

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/d/1/d1c3fefbb5cc112c19d6a9029489f0bced42e529.png)

I would like to create a DSL query in order to check minute by minute:

- number of documents with ACTION = "purchase" (paramA)
- number of documents with ACTION = "refund" (paramB)
- calculate incidence of purchases minute by minute as: paramA / total number of documents (in same minute)
- calculate incidence of refunds minute by minute as: paramB / total number of documents (in same minute)

I found documentation about "bucket\_script", but I'm not able to count Items, not sum them.  
[https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-bucket-script-aggregation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-bucket-script-aggregation.html)

My expectation is:  
minute 11:30:

- Number of documents: 6
- Number of purchases: 3
- Number of refunds: 3
- Incidence of purchases: 3 / 6 \* 100
- Incidence of refunds: 3 / 6 \* 100

Could you help me, please?
