Adrien Grand commented on LUCENE-4599:
--------------------------------------
I think a FST would not compress as much as what LZ4 or Deflate can do? But
maybe it could speed up TermsEnum.seekCeil on large documents so it might be an
interesting idea regarding random access speed?
bq. can we simply reference the terms by ord (an int) instead of writing each
term bytes?
Do you mean their ords in the terms dictionary? Is that information available
somewhere when writing/merging term vectors?
