Description

For single shard collections, Solr responds with the enum index instead of the value. For multi-shard collections, Solr returns a 500 because internally it gets a ClassCastException such as:

java.lang.ClassCastException: class org.apache.solr.common.EnumFieldValue cannot be cast to class java.lang.Integer
