--------------------------------------
Hi, [~thomascorthals] I am interested in working on this project. After
reviewing the documents and source code, I have a few questions and concerns
that I would like to clarify.
what is the difference between a child doc and a subdoc?
from what I understand from looking into the code,
when we have
{code:xml}
<doc>
<field name="id">1</field>
<field name="children">
<doc>
<field name="id">3</field>
</doc>
</field>
</doc>{code}
it is a nested child doc
when we have
{code:java}
<doc>
<field name="id">1</field>
<doc>
<field name="id">3</field>
</doc>
</doc> {code}
it is a subdoc, right?
> XML Loader: support indexing single nested child document

> Project: Solr

> Reporter: Thomas Corthals

> Labels: newbie
>
> The XML Loader always treats labelled nested children as a "multi-valued
> pseudo-field", whereas the JSON Loader can also index a single child document
> as well as an array of 1..n child documents.
> The XML Loader should have a corresponding syntax for a single labelled
> nested child.
