Research direction
The request concerns ToChildBlockJoinQuery and a proposed ToChildBlockJoinSortField, with the LUCENE-7835.patch attachment as the only implementation reference. Start by reviewing that patch and the linked issues, then determine how child documents should be compared by parent fields. Done means searches using ToChildBlockJoinQuery can sort child documents according to their parent fields.
