Block Join Faceting in JSON Facet API
Hi Yonik,
I’ve been working on [SOLR-5743] Faceting with BlockJoin support
<https://issues.apache.org/jira/browse/SOLR-5743>, and I think it would be
nice to integrate this functionality into JSON Facet API. Current JSON
options <http://yonik.com/solr-nested-objects/> provide either querying
child documents and faceting on parent ones, or vice versa, i.e. querying
parent documents and calculating facets on all their children. But for
typical eCommerce product/sku navigation it’s important to query parent
documents that have some specific children (using ToParentBlockJoinQuery)
and calculate correspondent facets. I.e. we need to calculate number of
parent documents that have matched children with particular attributes. In
example, provided on http://yonik.com/solr-nested-objects/, let’s suppose
that user searches books that have 5 star reviews and wants to have a facet
by authors with number of books (i.e. reviewing the same book again is not
counted).
It looks like neither blockChildren nor blockParent suite for this use
case. Do you have an idea of how to extend JSON facets to cover such usage?
Oleg

Yeah, I'll open a jira issue to go with it.

Hi Yonik,
Hope you had a great holiday.
Do you have some time to discuss JSON facets API extension?

Hi Oleg,
I agree, true "rollup" ability is needed in the JSON Facet API.
I'm currently on vacation... just happened to catch this message.
When I return next week, I'll try to communicate/contribute some
brainstorming I've been mulling around what the API might look like.
