getFirstValue problem with solrj

Hello

I have one problem

I made a query as foollws :

                     System.out.println("Querying by using SolrQuery...");
                     SolrQuery solrQuery = new SolrQuery("Name:" + Pattern);
                     solrQuery.addField("id");
                     solrQuery.addField("App_code");
                     solrQuery.setSort("App_code", ORDER.asc);
                     solrQuery.setRows(10);
                     QueryResponse response = null;
                     try {
                         response = 
AppServServlet.solrClientApps.query(solrQuery);
                     } catch (SolrServerException | IOException e) {
                         System.err.printf("\nFailed to search articles: 
%s", e.getMessage());
                     }

and got response as follows :

                     SolrDocumentList documents = null;
                     if (response != null) {
                             documents = response.getResults();
                             System.out.printf("Found %d documents\n", 
documents.getNumFound());
                             for (SolrDocument document : documents) {
                                 String id = (String) 
document.getFirstValue("id");
                                 String name = (String) 
document.getFirstValue("Name");
                                 long App_code1 = (long) 
document.getFirstValue("App_code");
                                 System.out.printf("id=%s, App_code=%s, 
name=%s\n", id, App_code1, name);
                             }
                      }

Found 1 document but name = (String) document.getFirstValue("Name"); 
returns null

Console looks like :

Querying by using SolrQuery...
Found 1 documents
id=0000000092, App_code=2, name=null

What is wrong ?

Please somebody helps me !

Regards

Raivo

0000000057 0  HIS
0000000045 1  RAN/AEGIR
