----------------------------------------

Hello,
I'd like to confirm what the "term" means in "unique terms". Is the term Term? (unique terms in whole fields in a single segment?) or word? (unique terms in each field in a single segment?). Thanks.

> Lucene can't handle more than 2.1B (limit of signed 32 bit int) unique terms in a single segment.
> But I think we can improve this to termIndexInterval (default 128) * 2.1B.  There is one place (internal API only) where Lucene uses an int but should use a long.
