[求助]MySQL全文检索问题

MySQL5.0utf-8编码CREATE   TABLE   `testtel`   (
    `tel`   varchar(25)   default   NULL,
    FULLTEXT KEY `tel` (`tel`)
)   TYPE=MyISAM; INSERT   INTO   `testtel`   (`tel`)   VALUES
    ( '020-1234567 '),
    ( '123456789000 '), mysql>   select   tel   from   testtel
->       where   MATCH   (tel)   AGAINST   ( '12345'  IN  BOOLEAN  MODE)
为什么查询结果为空呢？我分不多，只能给20了。
