             //  The expression to be added is NOT(department="HR")
             
                 SearchSettingGroup group = ....... // use existing or create new 
                 Keyword keyword = group.Keywords.AddKeyword("language");
             
                 var employeeContext = group.Contexts.AddContext("employee");
                 var employeeExpression = employeeContext.AddNotExpression();
                 employeeExpression.AddMatchExpression("department", "HR");
