Mikhail Khludnev commented on SOLR-8998:
----------------------------------------
[[email protected]] in these cases q= aims children explicitly. But one of the
desirable features for typical e-commerce is
bq. to search for parents which has children which are foo, get parent results,
get also child field facets rolled up to parents, in single query.
So far it seems like it requires to issue two request, which might be
unacceptable complex.
It.s not easy to achieve, do you accept it as challenge at all?
> JSON Facet API child roll-ups
> -----------------------------

> Key: SOLR-8998
> URL: https://issues.apache.org/jira/browse/SOLR-8998
> Project: Solr
> Issue Type: New Feature
> Components: Facet Module
> Reporter: Yonik Seeley
>
> 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.
