- MySQL 全文搜索支持
- 从MySQL 4.0以上 myisam引擎就支持了full text search 全文搜索,在一般的小网站或者blog上可以使用这个特性支持搜索。
- 那么怎么使用了,简单看看:
- 1.创建一个表,指定支持fulltext的列
- CREATE TABLE articles (
- id INT UNSIGNED AUTO_INCREMENT NOT NULL PRIMARY KEY,
- title VARCHAR(200),
- body TEXT,
- FULLTEXT (title,body)
- );
- 2.插入一些数据作为测试
- INSERT INTO articles (title,body) VALUES
- (‘MySQL Tutorial‘,‘DBMS stands for DataBase ...‘),
- (‘How To Use MySQL Well‘,‘After you went through a ...‘),
- (‘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 ...‘);
- 3.select查询fulltext的列
- SELECT * FROM articles
- WHERE MATCH (title,body) AGAINST (‘database‘);
- 查询结果:
- 5 MySQL vs. YourSQL In the following database comparison ...
- 1 MySQL Tutorial DBMS stands for DataBase ...
- 全文查询中的boolean语句, + -跟普通的搜索引擎语法一样
- SELECT * FROM articles WHERE MATCH (title,body)
- AGAINST (‘+MySQL -YourSQL‘ IN BOOLEAN MODE);
- innodb不支持fulltext,当然可以使用http://sphinxsearch.com/ sphinx来dump数据库数据支持全文搜索。
