删除停用词后,MYSQL查询未返回预期结果

I am trying to remove stop words from my local system having mysql version 5.5.38 . I searched for ft_stopword_file in /etc/mysql/my.cnf and couldn't find it. So I added the line

ft_stopword_file = ""

in that file and restarted the mysql server. Then repaired the indexes using

 REPAIR TABLE articles QUICK

I am using a table named articles which have structure like :

 mysql> CREATE TABLE articles (
        id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY,
        title VARCHAR(200),
        body TEXT,
        FULLTEXT (title,body)
      ) ENGINE=MyISAM;

 mysql> INSERT INTO articles (title,body) VALUES
      ('MySQL Tutorial','DBMS stands for DataBase ...'),
      ('Testing','Anything happened ...'),
      ('Optimizing MySQL','In this tutorial we will show ...'),
      ('1001 MySQL Tricks','1. Never run mysqld as root. 2. ...'),
      ('MySQL vs. YourSQL','In the following database comparison ...'),
      ('MySQL Security','When configured properly, MySQL ...');

I tried the FULLTEXT SEARCH query :

 SELECT * FROM articles  WHERE MATCH (title,body) AGAINST ('anything'); 

which returned 0 records even though there is one record with that word in articles table. Also I read from http://dev.mysql.com/doc/refman/5.5/en/fulltext-stopwords.html that stop words are listed in storage/myisam/ft_static.c, but I can't find out this folder in my LAMP.

Can anyone please help me to find out the problem? Thanks in advance
