Subject [jira] [Created] (SOLR-13129) Document nested child docs in the ref guide
Date Tue, 08 Jan 2019 20:58:00 GMT
David Smiley created SOLR-13129:
-----------------------------------

             Summary: Document nested child docs in the ref guide
                 Key: SOLR-13129
                 URL: https://issues.apache.org/jira/browse/SOLR-13129
             Project: Solr
          Issue Type: Sub-task
      Security Level: Public (Default Security Level. Issues are Public)
          Components: documentation
    Affects Versions: 8.0
            Reporter: David Smiley
             Fix For: 8.0


Solr 8.0 will have nicer support for nested child documents than its predecessors.  This
should be documented in one place in the ref guide (to the extent that makes sense). Users
need to the schema ramifications (incl. special fields and that some aspects are optional
and when), what a nested document "looks like" (XML, JSON, SolrJ), how to use the child doc
transformer, how to use block join queries, and get some overview of how this all works.  Maybe
mention some plausible future enhancements / direction this is going in (e.g. path query language?).
 Some of this is already done but it's in various places and could be moved.  Unlike other
features which conveniently fit into one spot in the documentation (like a query parser),
this is a more complex issue that has multiple aspects – more "cross-cutting", and so IMO
doesn't belong in the current doc pigeon holes.
