举例： select * from people where match(name) against('aaa’); 自然语言模式(NATURAL LANGUAGE MODE) select * from people where match(name) against('aaa*' in boolean mode); 可以使用in boolean mode修饰符执行布尔全文搜索 布尔操作符 说明 ('北京昌平') as '相似度评分' from full_test where match(address) against('北京昌平'); -- 查找包含北京或昌平的行 select * from (address) against('+北京 ~昌平' IN BOOLEAN MODE) as '评分' from full_test where match(address) against('+北京 (address) against('aa*' IN BOOLEAN MODE) 用法和中文全文解析一样，只是分词方式不一样

对于FULLTEXT索引的内容可以使用MATCH(column)…AGAINST(val)语法进行查询。 MySQL支持三种模式的全文检索模式： 自然语言模式(IN NATURAL LANGUAGE MODE)，即通过MATCH AGAINST 传递某个特定的字符串来进行检索。 空(也就是默认情况)，表示可选的，包含该词的顺序较高 SELECT title from t_full_text WHERE MATCH(title) AGAINST(‘今日头条 火箭赢了’) 3. SELECT title from t_full_text WHERE MATCH(title) AGAINST(‘+今日头条 9. 前面有通配符 SELECT title from t_full_text WHERE MATCH(title) AGAINST(‘*今日头条’ IN BOOLEAN MODE) 13.
