If you look carefully at the "caveats and limitations" for Atomic Updates, you will see that all copyField destinations must be unstored for proper operation: https://wiki.apache.org/solr/Atomic_Updates#Caveats_and_Limitations It appears that this information was *NOT* in the Solr Reference Guide, so I updated the reference guide to include it. https://cwiki.apache.org/confluence/display/solr/Updating+Parts+of+Documents Here's a question for those with more expertise than me: If a copyField destination were stored, but not multiValued, and an atomic update was attempted, would the update fail entirely? I suspect it would, and I'd like to make the ref guide info as accurate as I can. Thanks, Shawn
