Facet: define and use a function instead of the traditional count?

Look into using the value_script with the terms stats facet.

Hi folks,

I am wondering if it is possible, for any kind of facets, to define and
use a function instead of the count ?

Quick example:

I have a term facet on a field which can be Paid or Unpaid, and I got the
number of hits.

term: Paid
count: 12

term: Unpaid
count: 10

I also have another field "amount", and I am wondering if I can define a
function to say : for each match, add the amount to the sum.

term: Paid
count: 120 (for an amount of 10)

term: Unpaid
count: 100

Thanks for your help
