[jira] [Commented] (CONNECTORS-1045) Support for Solr Nested/Child documents

    [ https://issues.apache.org/jira/browse/CONNECTORS-1045?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14173827#comment-14173827 ] 

Swami Rajamohan commented on CONNECTORS-1045:
---------------------------------------------

Sorry for the delayed response. I didn't notice the response.
Our use case is that we have documents that are stored in the repository in a folder content hierarchy. However we do have another relationship among items wherein a content item(s) can belong to a folder and be contained within a parent document as well. The Solr Nested document provides us a way to query that relationship as a block join. The use case for this parent child relationship comes in the case where we build Topic web pages(parent) that have content items as children. The children items themselves would not make sense on its own but only in context within a parent. Everytime there is a change in the association with regards to the parent, all of the associated children and newly associated children & disassociated children will get updated as a single unit.

At query time the BlockJoinQuery parser of Solr will allow me to perform join operations https://cwiki.apache.org/confluence/display/solr/Other+Parsers#OtherParsers-BlockJoinQueryParsers

Hope this helps in clarifying the use case.

> It would be nice to have support for Solr's Nested/Child document submission feature, which allows documents to be indexed as children of a parent document.
