Hello,

We have a field in ELK 7.1.1 calculate like that :  
name field : RESULT  
script : doc['ORIG1BEFORE'].value-doc['ORIG2AFTER'].value

when we display it, it display 0 or other no null value.

When we do a filter in visualize filter with RESULT \>0 it display some value with 0 value

We don't understand why ...

if you have ideas.. thanks in advance

Can you describe your index shape a little more? What is `value-doc`?
