I was trying to filter out all documents that HAVE that field. I was trying to delete any documents where that field had empty values.
I just found a way to do it, but I did a range query on a string date in the Lucene DateTools format and it worked, so I'm satisfied. However, I believe it worked because all of my documents have values for that field. Oh well. -max On Wed, Aug 25, 2010 at 9:45 PM, scott chu (朱炎詹) <scott....@udngroup.com>wrote: > Excuse me, what's the hyphen before the field name 'date_added_solr'?
