mosh commented on SOLR-12768:
-----------------------------
{quote}I did _not_ include {{_nest_parent_}} as we don't actually use this
field for any features yet.
{quote}
Yeah, it should probably be up to the user to decide whether this field is to
be indexed.
It might benefit odd exotic queries.
{quote}<field name="_root_" type="string" indexed="true" stored="false"
docValues="false" />
{quote}
Currently there might not be a reason for root to be stored, but this could
change once SOLR-12638 comes around.
But I guess we could change it when dealing with that particular issue.
Just thought I would give a heads up.
The comments are a nice touch for each for field are a really nice touch.

> We know we need {{\_nest\_path\_}} in the schema for the new nested documents
> support, and we loosely know what goes in it. From a DocValues perspective,
> we've got it down; though we might tweak it. From an indexing (text
> analysis) perspective, we're not quite sure yet, though we've got a test
> schema, {{schema-nest.xml}} with a decent shot at it. Ultimately, how we
> index it will depend on the query/filter use-cases we need to support. So
> we'll review some of them here.
> TBD: Not sure if the outcome of this task is just a "decide" or wether we
> also potentially add a few tests for some of these cases, and/or if we also
> add a FieldType to make declaring it as easy as a one-liner. A FieldType
> would have other benefits too once we're ready to make querying on the path
> easier.
