Yes, it absolutely will require a complete reindex. A change like that probably will result in errors on queries until a reindex is done. You may even need to completely delete the index directory and restart Solr before doing your reindex to get rid of the old segments that have information incompatible with your new schema. http://wiki.apache.org/solr/HowToReindex Thanks, Shawn
