--------------------------------

    Attachment: SOLR-5285.patch

Updated patch with trunk.

bq. it's not clear to me from the API what to expect will happen if i have more then one level of parent-child relationships in my index – will children & grandchildren be returned? whatever is expected needs to be documented/tested

Tested with grandchildren. In Lucene all grandchildren and all siblings  are treated as simply children to the parent document. A parent document and all it's child documents are indexed in a block. Hence we should document for only support one level of nesting.

> Solr has added support for taking childDocs as input ( only XML till now ). It's currently used for BlockJoinQuery. 
> I feel that if a user indexes a document with child docs, even if he isn't using the BJQ features and is just searching which results in a hit on the parentDoc, it's childDocs should be returned in the response format.
> [~hossman_lucene@fucit.org] on IRC suggested that the DocTransformers would be the place to add childDocs to the response.
> Now given a docId one needs to find out all the childDoc id's. A couple of approaches which I could think of are 
> 1. Maintain the relation between a parentDoc and it's childDocs during indexing time in maybe a separate index?
> 2. Somehow emulate what happens in ToParentBlockJoinQuery.nextDoc() - Given a parentDoc it finds out all the childDocs but this requires a childScorer.
> Am I missing something obvious on how to find the relation between a parentDoc and it's childDocs because none of the above solutions for this look right.
