David Smiley commented on SOLR-12298:
-------------------------------------
bq. is that about right?
Yes; well put Hossman.
One other variation on an approach is to keep the \_childDocuments member of
SolrInputDocument but have it be a Map<String,List<SolrInputDocument>> to
capture the relationship name. It would probably be less work, although some
of the existing logic I spoke of would not "melt away" as I said. Shrug.
> Index Full nested document Hierarchy For Queries (umbrella issue)

> Key: SOLR-12298
> URL: https://issues.apache.org/jira/browse/SOLR-12298
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: mosh
> Priority: Major
>
> Solr ought to have the ability to index deeply nested objects, while storing
> the original document hierarchy.
> Currently the client has to index the child document's full path and level
> to manually reconstruct the original document structure, since the children
> are flattened and returned in the reserved "__childDocuments__" key.
> Ideally you could index a nested document, having Solr transparently add the
> required fields while providing a document transformer to rebuild the
> original document's hierarchy.
>
> This issue is an umbrella issue for the particular tasks that will make it
> all happen – either subtasks or issue linking.
