mosh commented on SOLR-12630:
-----------------------------
This is just a thought, but perhaps we could use something like the node
stream, except the transformer will rebuild the document structure instead of
only adding one field.
Another option is to query all documents by _root_, ordering by _nest_path_,
and rebuilding the original document structure from there.
The first option seems a lot more versatile, but I do admit I should probably
sleep on it, perhaps there is more to it then meets the eye.

> Key: SOLR-12630
> URL: https://issues.apache.org/jira/browse/SOLR-12630
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: mosh
> Priority: Major
>
> Currently work is being put into Solr to support nested document hierarchies,
> keeping the original relation between parent and child docs
> ([SOLR-12298|https://issues.apache.org/jira/browse/SOLR-12298],
> [SOLR-12441|https://issues.apache.org/jira/browse/SOLR-12441]). Currently the
> only way to query child documents is using BlockJoin. I was thinking perhaps
> we could introduce a way to query documents that are not indexed in the same
> block with a different transformer, or perhaps add this feature to the
> ChildDocTransformer.
