Adrien Grand commented on LUCENE-4599:
--------------------------------------
bq. I think we waste space with the terms, especially prefix/suffix lengths
[..] these should likely be bulk-compressed
Good point.
bq. flags are wasteful and stupid, but it seems like you already tried to
address that to some extent
I'm storing them in a packed ints array where each entry is 3 bits per value.
I'll try to optimize when a field always has the same flags.
