Subject Re: Faceting on both Parent and Child records in Block Join Query Parser
Date Tue, 04 Oct 2016 09:22:22 GMT
I have tried to use this nested query, but I still can't get results for
the list of books.

http://localhost:8983/solr/collection1/select?q=*:*
&json.facet={
   items:{
      type:terms,
      field:author_s,
 domain: { blockParent : "type_s:author" },
 facet:{
by1:{
type:terms,
field:book_s,
domain: { blockChild : "type_s:book" }
}
}
 }
   }
}&fl=null&rows=0


Only when I didn't use the nested method, but query it individually like
the one below, the I managed to get the result.

http://localhost:8983/solr/collection1/select?q=*:*
&json.facet={
   items:{
        type:terms,
        field:author_s,
  domain: { blockParent : "type_s:author" }
   },
   by1:{
type:terms,
field:book_s,
domain: { blockChild : "type_s:book" }
  }
}&fl=null&rows=0


Regards,
Edwin
