> The facets module has multiple facet methods for counting flat and hierarchical fields, and also a method for counting numeric ranges. I'd like to also add a method that counts unique numeric (long) values, designed to be used for fields that have only a few, typically low valued, numbers across the index e.g. a "review" rating from 1 to 5.
