MySQL-FULLTEXT模式匹配

我有一個MySQL-query由FULLTEXT -indexes組成，因爲我需要一個相關性排序。缺點是，我需要有模式匹配像MySQL-FULLTEXT模式匹配

SELECT * FROM table WHERE colum LIKE %word%

有沒有辦法在FULLTEXT -searches來實現這一點？

在全文搜索中，您可以使用'*'進行通配符搜索。所以說你有'aabbbbcc，bbbb，bbbbxyz'的數據，你可以使用布爾模式作爲匹配（列）針對（'bbbb *'IN布爾模式）' – 2015-03-02 10:43:17

是利用對陣全文搜索這樣

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

，如果你想從多個表進行搜索，那麼提表名用逗號分隔

我已經嘗試過這樣，但它不起作用。 .. – Force0234 2015-03-02 10:38:21

它給了什麼錯誤？ – TECHNOMAN 2015-03-02 10:43:54

在運行此查詢之前，您必須將該字段設置爲全文。爲了使這個使用sql查詢ALTER TABLE表名ADD FULLTEXT（fieldname）; – TECHNOMAN 2015-03-02 10:46:15

這裏是你如何使用MySQL full Text search：

在這裏，您不必爲打破更大的輸入字符串轉換成數組與每個單詞進行比較。

請參考下面的例子來寫自己：

是雙引號括起來（「「」）字符的短語匹配的

只是字面上包含該短語的行，因爲它是鍵入

我想解釋你有關Boolean Full Text Search;不過，我勸你請通過Full Text Search using Query Expansion也

讓我們看看示例表：

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

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

訂購事宜，當時的話被引用：

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

Empty set (0.01 sec)

當我們去掉引號，它將搜索行，包含單詞「數據庫」或「比較」：

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 ... | 
+----+---------------------+------------------------------------------+

順序並不重要，現在：

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 ... | 
+----+---------------------+------------------------------------------+

如果我們想要得到的行，包含無論是單詞「的PostgreSQL」或短語「數據庫的比較」，我們應該用這個請求：

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 ... | 
+----+---------------------+------------------------------------------+

確保，這樣的詞語，你正在搜索，不在list of stopwords中，那些被忽略。
