> You cannot sort on fields that don't exist
> ------------------------------------------
>
> Key: LUCENE-374
> URL: http://issues.apache.org/jira/browse/LUCENE-374
> Project: Lucene - Java
> Type: Bug
> Components: Search
> Versions: CVS Nightly - Specify date in submission
> Environment: Operating System: other
> Platform: Other
> Reporter: Daniel Naber
> Assignee: Yonik Seeley
> Fix For: 1.9
> Attachments: sort.diff, sort.diff, sort.diff
>
> While it's possible to search for fields that don't exist (you'll get 0
> hits),
> you'll get an exception if you try to sort by a field that has no values. The
>
> exception is this:
>
> if (termEnum.term() == null) {
> throw new RuntimeException ("no terms in field " + field);
> }
>
> I'll attach a change suggested by Yonik Seeley that removes this exception.
>
> Also, the if-condition above is incomplete anyway, so currently the exception
> is not always thrown (as termEnum .term() might well be != null but point to
> a
> term in a different field already)
