Subject [jira] [Commented] (LUCENE-3892) Add a useful intblock postings format (eg, FOR, PFOR, PFORDelta, Simple9/16/64, etc.)
Date Mon, 13 Aug 2012 13:56:38 GMT


Adrien Grand commented on LUCENE-3892:

bq. (From mailing-list) So I think if its this ambiguous for wikipedia we should shoot for
the most COMPACT form as a safe default.

+1 too. I just committed the change.
