删除mysql ft\u stopword\u文件后没有结果

我有一个电影数据库，里面有一部叫《是的，我们开着》的电影的信息

在搜索数据库时，我遇到了一个问题，搜索“yes we's open”会返回另一个标题，该标题的描述中有“we's”和“open”两个词，但没有“yes”，即使我需要布尔模式下的所有词（即，“yes we's open”在作为查询发送之前被翻译为

”+yes+we's+open'

）

我认为这是因为“是”在内置的停止词列表中。但是，当我设置

ft\u stopword\u file=“”

，重新启动mysql，然后

修复表[tablename]quick

我正在搜索的表时，搜索“是的，我们打开了”时没有得到任何结果。我在下面加入了我的.cnf。这是MySQL版本5.0.22。有什么想法吗

[mysqld]
query-cache-type = 1
query-cache-size = 8M
max_allowed_packet=500M
ft_min_word_len=2
ft_stopword_file = ""

[myisamchk]

编辑：以下是一些示例查询：

将stopwords.txt变量设置为空字符串（“”）将禁用所有。 （删除一些不需要…建议…的单词）

您创建的全文搜索索引需要销毁并创建新索引

更改此变量或stopword文件的内容后，必须重新生成全文索引

---

然后使用维修表tbl_name QUICK

InnoDB不支持表修复（当您快速修复表tbl_name时，可以看到一个注释。）

我找到的唯一解决方案是将引擎更改为MyISAM，尽管这可能会降低读写性能

如何在MySQL中禁用全文停止字：

在my.ini文本文件（MySQL）中：

//设置最小长度，但请注意，较短的单词（3,2）将显著增加查询时间，特别是当全文索引列字段较大时

保存文件，重新启动服务器

下一步应该是使用此查询修复索引：

REPAIR TABLE tbl_name QUICK.

但是，如果您的表使用InnoDB存储引擎，这将不起作用。您必须将其更改为MyISAM：

ALTER TABLE t1 ENGINE = MyISAM;

因此，再一次：

1. Edit my.ini file and save
2. Restart your server (this cannot be done dynamically)
3. Change the table engine (if needed)  ALTER TABLE tbl_name ENGINE = MyISAM;
4. Perform repair                       REPAIR TABLE tbl_name QUICK.

---

请注意InnoDB和MyISAM有它们的速度差异。一个读取速度更快，另一个写入速度更快（在internet上阅读更多相关信息）

请添加一个显示问题的查询（和结果）。执行“显示变量，如“ft%”，以获取当前设置。@wallyk我在上面添加了一些查询和结果。如果您需要更多信息，请告诉我。@JuanMellado我在上面添加了您要求的内容。请显示

SHOW CREATE TABLE db.films\G

我不需要任何停止词，因为我网站上的绝大多数搜索都是为了确切的电影标题。如果你看一下我原来的问题，你会发现每次我更改stopword文件时，我都会快速完成修复表tbl_name。你是否销毁并创建了新的索引全文搜索？然后再次检查维修台。

1. Edit my.ini file and save
2. Restart your server (this cannot be done dynamically)
3. Change the table engine (if needed)  ALTER TABLE tbl_name ENGINE = MyISAM;
4. Perform repair                       REPAIR TABLE tbl_name QUICK.
