hi guys,  
I’m new with ES and I need your help 😊

I working on a system that needs to show the history of the data it’s got- what field changed, what is the new value, and when did it change. 🤯

The historical view is kinda like git diffs

Imagine an object called Person, with the fields: age,birth-date,address(country,city,street…),cellphone.  
The system gets updates of Person objects, and sometimes updates doesn’t change any value.  
But, when a person dies, the object has different fields: age,birth-date,time-of-death.  
On the history view I want to easily see the changes over specific Person in a specified time-range.

How should I store the data in that case?  
And How should I query the data with minimum manipulations “outside” the ES?

Thanks
