I have an index like that :
I have an ID which could have a list of detail contact.
In my vizualisation, I try to display the number of contacts per channel.
The result is 2 SMS and 2 EMAIL whereas i was expecting 1 SMS and 1 EMAIL.
Moreover, I don't understand in the discover, why the field details_contact.jour_contact is extracted from the json document and not the other fields.
Any idea ?
