I have a document which can be modified any number of times a day. I've ordered these document in time series creating index for each day. And each day would have multiple versions of the same document with different modified date.

Document sample:

{  
id: 1234,  
user: kc,  
subscriptions: [  
'paper1',  
'paper2'  
],  
modified\_date: 1466697434020  
}  
What I'm looking for is to get the latest documents in a particular time range for all users and to apply aggregation on top of it.

That would give a result like, in the last week/month how many people are subscribed for each of the papers.

Using top\_hits I was able to get the latest document for different users in a time range, but I cannot apply further aggregations on this set of data.

Suggestions are welcomed, for changing the data model to achieve this.
