                "KnowledgeArticleVersion", "Question"});
        
        // Get the properties of each data category group 
        for (int i = 0; i < results.length; i++) {
          System.out.println("sObject: " + 
              results[i].getSobject());
          System.out.println("Group name: " + 
              results[i].getName());
          System.out.println("Group label: " + 
              results[i].getLabel());

          System.out.println("Number of categories: " + 
              results[i].getCategoryCount());
