问题描述
我有一个包含一些像这样的关键字的字符串$string = 'one, two, "phrase three words"'我正在尝试使用以下内容进行全文搜索:
I have a string that contains some keywords like this $string = 'one, two, "phrase three words"'I am trying to do a full-text search using:
SELECT *, MATCH (column) AGAINST ('$string') AS score,
FROM table WHERE MATCH (column) AGAINST ('$string' IN BOOLEAN MODE) ORDER BY score DESC
当MySql返回结果时，关键字短语3个单词"不作为短语匹配，但其中的每个单词都作为一个单词匹配.
When MySql gives back the results, the keyword "phrase three words" is not matched as a phrase, but every word from it is matched as a single.
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?我已经尝试过使用stripslashes()作为字符串，但是结果是相同的.
How should I modify the string or the query to receive the results where the whole phrase matches? I have tried with stripslashes() for the string, but the result is the same.

为 MySQL 手册说:
让我们看一下示例表:

+----+-------------------+------------------------------------------+
引号中的顺序很重要:
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:
When we remove the quotes, it will search for rows, containing words "database" or "comparison":
mysql> SELECT * FROM articles WHERE MATCH (title,body)
AGAINST ('database comparison' IN BOOLEAN MODE);
+----+---------------------+------------------------------------------+
| id | title | body |

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

+----+---------------------+------------------------------------------+
如果要获取包含单词"PostgreSQL"或短语数据库比较"的行，则应使用此请求:
If we want to get rows, containing either word "PostgreSQL" or phrase "database comparison", we should use this request:
mysql> SELECT * FROM articles WHERE MATCH (title,body)
AGAINST ('PostgreSQL "database comparison"' IN BOOLEAN MODE);
+----+---------------------+------------------------------------------+
| id | title | body |
+----+---------------------+------------------------------------------+

+----+---------------------+------------------------------------------+
请确保您要搜索的单词不在停用词列表，将被忽略.
Make sure, that the words, you are searching for, are not in the list of stopwords, that are ignored.
