> The JSON Facet API currently has the ability to map between parents and
> children ( see http://yonik.com/solr-nested-objects/ )
> This issue is about adding a true rollup ability where parents would take on
> derived values from their children. The most important part (and the most
> difficult part) will be the external API.

> The bottom line is to introduce {{uniqueBlock(\_root_)}} aggregation, which
> is supposed to be faster than {{unique(\_root_)}} and purposed for blocked
> index only. For now it it supports singlevalue string fields, docValues
> usually make sense.
