> Facets can be aggregated today by counting them, aggregating by summing their
> association values, or summing the scores of the documents. Applications can
> write their own FacetsAggregator to compute the value of the facet in other
> ways. Following the new expressions module, I think it will be interesting to
> allow aggregating facets by arbitrary expressions, e.g. {{_score *
> sqrt(price)}} where 'price' is an NDV field. I'd like to explore allowing any
> ValueSource to be passed in and write a ValueSourceFacetsAggregator.
