As discussed in SOLR-12298, to make use of the meta-data fields in
SOLR-12441, there needs to be a smarter child document transformer, which provides the ability to rebuild the original nested documents' structure.
In addition, I also propose the transformer will also have the ability to bring only some of the original hierarchy, to prevent unnecessary block join queries. e.g.
Incase my query is for all the children of "a:b", which contain the key "e" in them, the query will be broken in to two parts:
1. The parent query "a:b"
2. The child query "e:*".
If the only children flag is on, the transformer will return the following documents:
In case the flag was not turned on(perhaps the default state), the whole document hierarchy will be returned, containing only the matching children:
