SQL中的SCORE声明给出以下错误

Question

我试图用SCORE执行以下查询

SELECT DISTINCT ID, SCORE 
FROM (
  SELECT DISTINCT ID,SCORE(1) AS SCORE,NAME 
  FROM TESTTABLE 
  WHERE CONTAINS (NAME,'ABOUT(Test)', 1) > 34 ORDER BY UPPER(NAME) 
) 
where rownum <= 100 
order by score desc

但它正在抛出 ORA-29908：缺少辅助运营商的主要调用

无法找出原因。 TIA的帮助
