How to retrieve nested documents (parents and their children together) ?
https://lucene.apache.org/solr/guide/7_4/other-parsers.html#block-join-parent-query-parser
talks about {!parent which=} docs>, which returns parent docs only, and
{!child of=} , which
returns child docs only.
Is there a way to retrieve the matched documents in the original, nested form?
Using the sample document, is there way to get:
1
Solr has block join support
parentDocument
2
SolrCloud supports it too!
rather than just the parent or the child docs?
Re: How to retrieve nested documents (parents and their children together) ?
Hello,
Check [child]
https://lucene.apache.org/solr/guide/7_4/transforming-result-documents.html#child-childdoctransformerfactory
or [subquery].
Although, it's worth to put reference to it somewhere in blockjoin
qparsers.
Documentation patches are welcome.

Solr [subquery] document transformer
Good afternoon knowledgeable solr community. I’m experiencing problems using a
document transformer across a multiple shard collection and am wondering if
anyone would please be able to assist or provide some guidance?
The document transformer query below works nicely until I split the collection
into multiple shards and then I receive what appears to be an authentication
issue on the subquery.
My query configuration (the original query returns a document with a field link
to another ‘parent’ document)
"parent.q":"{!edismax qf=CHILD_ID v=$row.PARENT_ID _route_=PARENT_ID!}",
"parent.fl":"*",
"parent.rows":1,
"fl":"…other fields to display, parent:[subquery]",
Environment:
SolrCloud (7.3.1)
Https
Rules based authentication provider
Any advice would be appreciated.
