Thanks. I fixed the schema and it's working now. Also my other problem of "not all defined fields showing up in the results" is also resolved. I found out last night that Solr is case-sensitive. I typed all fields in the schema in lower-case, and my CSV files had mixed cases for some of the fields. These mixed case fields do not show up in the XML results. Sorry, I've been working in the Windows environment for so long and forgot about Unix-case-sensitive environment.
