Fwd: Block Joins

[Rick Leir]

Hi all,
I am new to Block Joins, and am trying to follow
https://cwiki.apache.org/confluence/display/solr/Other+Parsers#OtherParsers-BlockJoinQueryParsers

This page shows two forms of block join

syntax for this parser   q={!child of=<allParents>}<someParents>.
example query            q={!child
of="content_type:parentDocument"}title:lucene
return output is the children.

syntax for this parser   q={!parent which=<allParents>}<someChildren>
example query            q={!parent
which="content_type:parentDocument"}comments:SolrCloud
return output is their parents.


Is it possible to get a list of the matching children, along with the
parent record? I have tried


$ curl http://localhost:8983/solr/dorsetdata/query -d '
q={!parent which="content_type:parentDocument"} type_s:page AND civilian&
wt=json&indent=true&fl=score,*,[docid]'

This gives me just the parent record's fields.

$ curl http://localhost:8983/solr/dorsetdata/query -d '
q={!child of="content_type:parentDocument"}&
wt=json&indent=true&fl=score,*,[docid]'

This gives me a list of parent records.

$ curl http://localhost:8983/solr/dorsetdata/query -d '
q={!child of="content_type:parentDocument"} type_s:book AND
publication_type:journal&
wt=json&indent=true&fl=score,*,[docid]'

This gives me the child records but no info from the parent record.



Compare this with normal faceting:

$ curl http://localhost:8983/solr/dorsetdata/query -d '
q=that&fl=canonicalMaster&
json.facet={
   hits : {
      type: terms,
      field: pkey
   }
}'

This just gives me fields from the children records.

Compare this with faceting on parents:

curl http://localhost:8983/solr/dorsetdata/query -d '
q=that&
fl=*&
json.facet={ hits :
     { type: terms,
       field: pkey,
       domain:
          { blockParent : "type_s:book" } } }'

This gives me fields from the children, and a list of parents, but not
fields from the parent records.

But what I need is fields from the matching children, along with fields
from the parent record.
