>                 Key: SOLR-12711
>                 URL: https://issues.apache.org/jira/browse/SOLR-12711
>             Project: Solr
>          Issue Type: New Feature
>          Components: Facet Module
>            Reporter: Mikhail Khludnev
>            Priority: Major

> h2. Context
> {{uniqueBlock(_root_)}} which was introduced in SOLR-8998 allows to count child field facet grouping hits by parents, ie hitting every parent only once.
> h2. Problem
> How to count only dominating child field value. ie if a product has 5 Red skus and 2 Blue, it contributes {{Red(1)}}, {{Blue(0)}}
> h2. Suggestion
> Introduce {{dominatingBlock(_root_)}} which aggregate hits per parent, chooses the dominating one and incs only it.
> h2. Further Work
> Judge dominating value not by number of child hits, but by the given function value. Like pick the most popular, best selling, random child field value as dominating.
