Currently only half supported.  By this I mean we can do math on
fields and aggregate them per bucket.
Basically sum(div(sold_products,products)), assuming products and
sold_products exist on each document.

What we can't do yet is do math on aggregations:
  div(sum(sold_products),sum(products))

If the former works for you, simply place that in a facet block within
a parent facet (like your range facet).

JSON Facet API Virtual Field Support

[Furkan KAMACI]

Hi,

I test JSON Facet API of Solr. Is it possible to create a virtual field
which is generated by using existing fields at response and supports
elementary arithmetic operations?

Example:

Schema fields:

products,
sold_products,
date

I want to run a date range facet and add another field to response which is
the percentage of sold products (ratio will be calculated as sold_products
* 100 / products)

Kind Regards,
