Subject [jira] Updated: (LUCENE-374) You cannot sort on fields that don't exist
Date Wed, 28 Sep 2005 01:52:47 GMT
     [ ]

Yonik Seeley updated LUCENE-374:

    Attachment: sort.diff

Updated my original patch from
which actually wasn't meant to be a complete patch, but just a template for one.

This patch removes the "no terms in field" exception for all the types except Auto, which
people probably shouldn't use anyway.
I think it's important for the reasons detailed in that thread.
