如果在顺序无关紧要的任何地方都需要Fiat和500，则

If you need Fiat and 500 anywhere where order does not matter, then

SELECT * FROM models MATCH(name) AGAINST('+Fiat +500');

如果同时需要Fiat 500，则

SELECT * FROM models MATCH(name) AGAINST('+"Fiat 500"');

如果您需要Fiat和零个或多个500，则

If you need Fiat and zero or more 500, then

SELECT * FROM models MATCH(name) AGAINST('+Fiat 500');

如果您需要500和零个或多个Fiat，则

If you need 500 and zero or more Fiat, then

SELECT * FROM models MATCH(name) AGAINST('Fiat +500');

尝试一下！

这是FULLTEXT搜索的默认设置

Here are the default settings for FULLTEXT searching

mysql> show variables like 'ft%';
+--------------------------+----------------+
| Variable_name            | Value          |
+--------------------------+----------------+
| ft_boolean_syntax        | + -><()~*:""&| |
| ft_max_word_len          | 84             |
| ft_min_word_len          | 4              |
| ft_query_expansion_limit | 20             |
| ft_stopword_file         | (built-in)     |
+--------------------------+----------------+
5 rows in set (0.00 sec)

mysql>

请注意 ft_min_word_len 默认为4.令牌500的长度为3.因此它根本不会被索引.您将必须做三(3)件事:

Notice that ft_min_word_len is 4 by default. The token 500 is length 3. thus it will not be indexed at all. You will have to do three(3) things:

将此添加到/etc/my.cnf

[mysqld]
ft_min_word_len = 1

STEP 02:重新启动mysql

service mysql restart

STEP 03:重新索引models表中的所有索引

您可以拖放并添加FULLTEXT索引

STEP 03 : Reindex all indexes in the models table

You could just drop and add the FULLTEXT index

或分阶段进行，看看它会提前多大

or do it in stages and see how big it will get in advance

CREATE TABLE models_new LIKE models;
ALTER TABLE models_new DROP INDEX name;
ALTER TABLE models_new ADD FULLTEXT name (name);
ALTER TABLE models_new DISABLE KEYS;
INSERT INTO models_new SELECT * FROM models;
ALTER TABLE models_new ENABLE KEYS;
ALTER TABLE models RENAME models_old;
ALTER TABLE models_new RENAME models;

当您对此工作感到满意时，请运行

When you are satisfied this worked, then run

DROP TABLE models_old;
