{quote}A ticket for the RTG handler(RealTimeGetComponent#process).
{quote}
I was thinking about this one, it has been a tough one alright!
 Wouldn't this result in a major difference from an API perspective between the 
search component and the RTG component?
 When querying a document by id, unless ChildDocTransformer is specified in the 
fl, only the matching document is returned.
 The same applies to the RTG handler. When a request is made where 
ChildDocTranformer is supplied, the whole block is returned.
 This makes sense to me,
 unless there is a specific need for the "/get" handler to possess the ability 
of returning the whole block if exists,
 I can not foresee any reason for this change.
 Unless, of course, there is a concrete requirement for this logic during the 
replication process.

> Currently Solr's RealTimeGet component return the document if provided a 
> docId when consulting the index. For AtomicUpdates for child documents, RTG 
> should return the whole block when dealing with a nested schema.
