Hi Julia,
Keep in mind that in order to facet on child document fields you'll need to
use the block join facet component:
https://lucene.apache.org/solr/guide/7_4/blockjoin-faceting.html
For the query itself you probably need to specify each required attribute
value, but looks like you're already
Whats' your current query? It's probably a question of building boolean
query by combining Solr queries.
Note, this datamodel might be a little bit overwhelming, So, if number of
distinct attributename values is around a thousand, just handle it via
dynamic field without nesting docs:
brass
