Michael McCandless updated LUCENE-4677:
---------------------------------------
Attachment: LUCENE-4677.patch
Initial patch ... not committable until I add a back-compat layer somehow ...
(how come TestBackCompat isn't failing...).
I tested Kuromoji's TokenInfo FST, temporarily turning off packing: vInt
encoding made the non-packed FST ~12% smaller (good!). The packed FST is
unchanged in size.
Then I tested on a bigger FST (AnalyzingSuggester build of FreeDB's song
titles) and the resulting FST is nearly the same size (1.0463 GB for trunk and
1.0458 with patch).
