Mikhail Khludnev commented on SOLR-12298:
-----------------------------------------

bq. I'm proposing removing explicit SolrInputField._childDocuments in favor of having fields
contains child document values.
[~dsmiley], I've found some by considerations by [~hossman] [here|https://issues.apache.org/jira/browse/SOLR-3535?focusedCommentId=13295189&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-13295189].
Personally I don't have strong opinion.

> 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.
