I didn't know about the timestamp update processor. That's pretty cool, and now that I really think about it, would be required for SolrCloud to operate sanely. If you're not running SolrCloud, then it can be handled with a config that's even easier. You can add a field like the following to your schema, and make sure that your indexing never includes this field: <field name="index_last_mod_internal" type="tdate" indexed="true" stored="true" docValues="true" default="NOW"/> That's copied straight out of one of the schemas I'm using. Thanks, Shawn
