[jira] [Commented] (LUCENE-7548) Docvalues sorting treats empty values as the default

["Erick Erickson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-7548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15652963#comment-15652963 ] 

Erick Erickson commented on LUCENE-7548:
----------------------------------------

BTW, interestingly the /export handler _seems_ to sort in the correct order, but /select doesn't. I admit I didn't look very closely, but thought it worth mentioning.

> I found this working on Solr, Mike suggested I raise it as a Lucene issue.
> This was for int fields, I'll assume the same holds for other types.
> The sort order is as though the null field was explicitly set to zero, the whole idea of sorting missing first is lost.
> doc1
> int_dv = 0
> int_sort = 1
> doc2
> int_sort=2
> doc3
> int_dv = 0
> int_sort=3
> sort by int_dv asc,int_sort asc gives
> doc1
> doc2
> doc3
> when it should give
