Is a field not larger than another field in the same document?

Question

elasticsearch

Hi friends.
I want to find documents in which one field is not equal to another field in the same document.
I will not think as a condition to put.
there are 2 fields in one document floor and floors (floor and floors in the house)
you need to select docks in which floor != floors (ie not the last floor).
Not the first floor is calculated simply (range gt: 1), but I can’t figure out how “not the last” is.
