Michael McCandless updated LUCENE-3729:
---------------------------------------

    Attachment: LUCENE-3729.patch

New patch, still just prototyping on FC, but now all tests pass.

I enabled packing and the wikipedia title data is now ~43.8% smaller than what FC does today
(PagedBytes + PackedInts).

Results are about the same as before:
