Subject What is the maximum document number?
Date Sun, 03 Jun 2012 18:18:15 GMT
Doing a little more research on document numbers, I had thought that the maximum document number
was 2^30-1 or Integer.MAX_INT, but... I see that IndexReader.numDocs, maxDoc, and the corresponding
IndexWriter methods return the number of documents as an int, so since document numbers start
at zero, the number of documents is actually limited to 2^30-1, so the highest document number
is limited to 2^30-1 minus another 1 or 2^30-2.
