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.

>  - blocks must not interleave,
>  - parents must remain at the end of the blocks
