Subject [jira] Updated: (SOLR-1299) In distributed search cannot search on any schema field in ascending order (descending is OK)
Date Thu, 23 Jul 2009 20:29:14 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1299?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Shalin Shekhar Mangar updated SOLR-1299:
----------------------------------------

    Attachment: SOLR-1299.patch

Here's a patch which adds a fix and a test which fails without the change. I added a new comparator
method which mimics the MissingStringLastComparatorSource before SOLR-1111.

I don't know much about distributed search to know if this is the "right" fix. I wouldn't
commit this until Yonik reviews and approves.
