Part of it has just recently been commited to trunk actually... https://issues.apache.org/jira/browse/SOLR-2802 https://builds.apache.org/job/Solr-trunk/javadoc/org/apache/solr/update/processor/ConcatFieldUpdateProcessorFactory.html ...with that, it's easy to say "anytime multiple values are found for a single valued string field, join them together with a comma". the only piece that's missing is to "copy" from a source field in an (earlier) UpdateProcessor. Theres a patch for this in SOLR-2599 but i haven't had a chance to look at it yet. -Hoss
