Subject [jira] Commented: (LUCENE-406) sort missing string fields last
Date Sun, 16 Jul 2006 19:35:15 GMT
    [ http://issues.apache.org/jira/browse/LUCENE-406?page=comments#action_12421467 ] 
            
Hoss Man commented on LUCENE-406:
---------------------------------

Note to anyone who may stumble upon this issue: the attached version was the initial implimentation,
it has since been commited to the Solr project, where bug fixes/improvements have been found....

http://svn.apache.org/viewvc/incubator/solr/trunk/src/java/org/apache/solr/search/MissingStringLastComparatorSource.java?view=log

...this issue still exists (in my mind) to migrate this functionality into the Lucene core
.. but it's not a very urgent priority.
