  Solr has blo         


        

Answer 1

For your use case you can just multiple block join filters:

q=*:*&
fq={!parent which="content_type:accommodation"}(+type:comment +comments:SolrCloud)&
fq={!parent which="content_type:accommodation"}(+type:publisher +address:England)

the first filter clouse will find which parent documents have a child which satisfies condition (+type:comment +comments:SolrCloud).

The second filter clouse will operate over subset of parent documents that satisfy the first filter. And it will find in this subset the parent documents that satisfy condition (+type:publisher +address:England).
