关于全文索引的停止词

全文索引不针对非常频繁的词做索引，

如this,you,my等

全文索引：在mysql的默认情况下，对于中文意义不大

因为英文有空格，标点符号来拆成单词，进而对单词进行索引，

而对于中文，没有空格来隔开单词，mysql无法识别每个中文词。

create table artical(

id int primary key auto_increment,

title varchar(200),

body text,

fulltext (title,body)

)engine=myisam charset utf8;

insert into artical

(title,body)

values

("how to use ","this is a table of healthy"),

("MySQL vs. YourSQL ","In the following database ");

select id,match(title,body) against("database") from artical;

select * from artical where match (title,body) against ("database");
