Adrien Grand updated LUCENE-5312:
---------------------------------
Attachment: LUCENE-5312.patch
Here is a patch that contains a new BlockJoinSorter abstract class, which
allows for reordering documents without breaking index-time blocks. The order
of parents and the order of children within the same parent can be configured
separately.
> Block-join-friendly index sorting

> doesn't break index-time blocks:
> - blocks must not interleave,
> - parents must remain at the end of the blocks
