-----------------------------
Resolution: Not A Problem
Assignee: (was: Lucene Developers)
I created an index with one empty document, ran a search with MatchAllDocsQuery
and a Sort on a field that doesn't exist, and the search returned 1 result, no
RuntimeExceptions thrown. Since this issue is inactive for a long time, and I
don't seem to be able to reproduce it, I'm closing it.
> Warnings needed for sorting on non existant or non indexed fields

> Key: LUCENE-459
> URL: https://issues.apache.org/jira/browse/LUCENE-459
> Project: Lucene - Java
> Issue Type: Bug
> Components: Search
> Affects Versions: CVS Nightly - Specify date in submission
> Environment: Operating System: other
> Platform: Other
> Reporter: Daniel Naber
> Priority: Minor
>
> 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)
