Hi everyone,

I want to create a chart using timelion to show me the unique users since the begining for a month.  
I want to count the user only in the first month of usage and if it appears in the following months to not count it at all.  
For the moment I managed to get the uniques in a month using: .es(metric='cardinality:username.keyword').

Looks like you're needing to consolidate information around a user and/or session entity in order to do this type of analysis. [Entity-centric indexing](https://www.youtube.com/watch?v=yBf7oeJKH2Y3) is a common pattern that may help you achieve this.
