Subject [jira] Commented: (LUCENE-2257) relax the per-segment max unique term limit
Date Tue, 18 May 2010 09:21:41 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12868569#action_12868569

Michael McCandless commented on LUCENE-2257:
--------------------------------------------

Yes, the limit is number of unique terms per-segment.

Flex actually increases the limit (the limit is per-field, per-segment; but in trunk, the
limit is across all fields).

> 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.
