MySQL-FULLTEXT模式匹配

我有一个MySQL-query由FULLTEXT -indexes组成，因为我需要一个相关性排序。缺点是，我需要有模式匹配像MySQL-FULLTEXT模式匹配

SELECT * FROM table WHERE colum LIKE %word%

有没有办法在FULLTEXT -searches来实现这一点？

在全文搜索中，您可以使用'*'进行通配符搜索。所以说你有'aabbbbcc，bbbb，bbbbxyz'的数据，你可以使用布尔模式作为匹配（列）针对（'bbbb *'IN布尔模式）' – 2015-03-02 10:43:17

是利用对阵全文搜索这样

SELECT * FROM表名WHERE MATCH（COLUMNNAME）AGAINST（ '值'）;

，如果你想从多个表进行搜索，那么提表名用逗号分隔

我已经尝试过这样，但它不起作用。 .. – Force0234 2015-03-02 10:38:21

它给了什么错误？ – TECHNOMAN 2015-03-02 10:43:54

在运行此查询之前，您必须将该字段设置为全文。为了使这个使用sql查询ALTER TABLE表名ADD FULLTEXT（fieldname）; – TECHNOMAN 2015-03-02 10:46:15

这里是你如何使用MySQL full Text search：

在这里，您不必为打破更大的输入字符串转换成数组与每个单词进行比较。

请参考下面的例子来写自己：

是双引号括起来（““”）字符的短语匹配的

只是字面上包含该短语的行，因为它是键入

我想解释你有关Boolean Full Text Search;不过，我劝你请通过Full Text Search using Query Expansion也

让我们看看示例表：

mysql> select * from articles; 
+----+-----------------------+------------------------------------------+ 
| id | title     | body          | 
+----+-----------------------+------------------------------------------+

| id | title    | body          | 
+----+-------------------+------------------------------------------+ 
| 5 | MySQL vs. YourSQL | In the following database comparison ... | 
+----+-------------------+------------------------------------------+

订购事宜，当时的话被引用：

mysql> SELECT * FROM articles WHERE MATCH (title,body) 
    AGAINST ('"comparison database"' IN BOOLEAN MODE); 

Empty set (0.01 sec)

当我们去掉引号，它将搜索行，包含单词“数据库”或“比较”：

mysql> SELECT * FROM articles WHERE MATCH (title,body) 
    AGAINST ('database comparison' IN BOOLEAN MODE); 

+----+---------------------+------------------------------------------+ 
| id | title    | body          | 
+----+---------------------+------------------------------------------+ 
| 1 | PostgreSQL Tutorial | DBMS stands for DataBase ...    | 
| 5 | MySQL vs. YourSQL | In the following database comparison ... | 
+----+---------------------+------------------------------------------+

顺序并不重要，现在：

mysql> SELECT * FROM articles WHERE MATCH (title,body) 
    AGAINST ('comparison database' IN BOOLEAN MODE); 

+----+---------------------+------------------------------------------+ 
| id | title    | body          | 
+----+---------------------+------------------------------------------+ 
| 1 | PostgreSQL Tutorial | DBMS stands for DataBase ...    | 
| 5 | MySQL vs. YourSQL | In the following database comparison ... | 
+----+---------------------+------------------------------------------+

如果我们想要得到的行，包含无论是单词“的PostgreSQL”或短语“数据库的比较”，我们应该用这个请求：

mysql> SELECT * FROM articles WHERE MATCH (title,body) 
    AGAINST ('PostgreSQL "database comparison"' IN BOOLEAN MODE); 

+----+---------------------+------------------------------------------+ 
| id | title    | body          | 
+----+---------------------+------------------------------------------+ 
| 1 | PostgreSQL Tutorial | DBMS stands for DataBase ...    | 
| 5 | MySQL vs. YourSQL | In the following database comparison ... | 
+----+---------------------+------------------------------------------+

确保，这样的词语，你正在搜索，不在list of stopwords中，那些被忽略。
