我有一个包含一些关键字的字符串，$string = 'one, two, "phrase three words"'
我正在尝试使用以下方法进行全文搜索：
SELECT *, MATCH (column) AGAINST ('$string') AS score,
FROM table WHERE MATCH (column) AGAINST ('$string' IN BOOLEAN MODE) ORDER BY score DESC
当MySql返回结果时，关键字“词组三词”不是作为词组匹配的，而是来自其中的每个词作为单个词进行匹配。
我应该如何修改字符串或查询以接收整个短语匹配的结果？我已经尝试使用 stripslashes() 作为字符串，但结果是一样的。
正如MySQL手册所说：
包含在双引号 (“"”) 字符中的短语仅匹配按字面意思包含该短语的行，因为它是键入的。
让我们看一下示例表：
mysql> select * from articles;
+----+-----------------------+------------------------------------------+
| id | title | body |

顺序很重要，当引用这些词时：
mysql> SELECT * FROM articles WHERE MATCH (title,body)
AGAINST ('"comparison database"' IN BOOLEAN MODE);
Empty set (0.01 sec)
当我们删除引号时，它将搜索包含单词“database”或“comparison”的行：
mysql> SELECT * FROM articles WHERE MATCH (title,body)
AGAINST ('database comparison' IN BOOLEAN MODE);
+----+---------------------+------------------------------------------+
| id | title | body |
+----+---------------------+------------------------------------------+

订单现在无关紧要：
mysql> SELECT * FROM articles WHERE MATCH (title,body)
AGAINST ('comparison database' IN BOOLEAN MODE);
+----+---------------------+------------------------------------------+
| id | title | body |
+----+---------------------+------------------------------------------+

| 5 | MySQL vs. YourSQL | In the following database comparison ... |
+----+---------------------+------------------------------------------+
如果我们想要获取包含单词“PostgreSQL”或短语“数据库比较”的行，我们应该使用这个请求：
mysql> SELECT * FROM articles WHERE MATCH (title,body)
AGAINST ('PostgreSQL "database comparison"' IN BOOLEAN MODE);
+----+---------------------+------------------------------------------+
| id | title | body |
+----+---------------------+------------------------------------------+

| 5 | MySQL vs. YourSQL | In the following database comparison ... |
+----+---------------------+------------------------------------------+
确保您正在搜索的单词不在stopwords 列表中，被忽略。
