Question about QueryParser

["James liu"]

public class AnalyzerTest {
   @Test
   public void test() throws ParseException {
       QueryParser parser = new MultiFieldQueryParser(new String[]{"title",
"body"}, new StandardAnalyzer());
       Query query1 = parser.parse("中文");
       Query query2 = parser.parse("中 文");
       System.out.println(query1);
       System.out.println(query2);
   }
}


output :

title:"中 文" body:"中 文"
(title:中 body:中) (title:文 body:文)



why they not  same?
