Hi David, I think you should add this option : flatten=true
and the could you try to use this XPath : /MedlineCitationSet/MedlineCitation/AuthorList/Author see here for the description : http://wiki.apache.org/solr/DataImportHandler#Configuration_in_data-config.xml-1 I don't think the that the commonField option is needed here, I think you should suppress it.
