It seems that since the index document number value is a positive int, =
this restricts the number of documents in an index to ( 2^31 - 1 ) =3D =
2,147,483,647.

Do I misunderstand?

I mean, that's enough for me, but it seems a kind of surprising =
restriction, considering long could be used instead for unimaginably =
large numbers of documents.  Well, I grant I probably can't imagine 2 =
billion documents either, but google can.

Just curious, sorry to bother anyone.
