Hi Erick, The name field is stored. I experience problem only when I update multiValued field with multiple values like, * <field name="skills" update="set">solr</field>* * <field name="skills" update="set">lucene</field>* * * It works perfect, when I set single value for multiValued field like, *<field name="skills" update="set">solr</field>*
