SQL 2008：关闭全文搜索查询的停用词 [英] SQL 2008: Turn off Stop Words for Full Text Search Query

问题描述

假设我有一个Company表，其中有一列名为名称。我有这个专栏的全文目录。如果用户搜索非常好的公司，我的查询将是：

  SELECT 
 * 
 FROM 
公司
其中
 CONTAINS（名称，'非常和良好AND公司'）
  

问题是在这个例子中，Very一词出现在停用词的标准列表中：

  SELECT 
 ssw。* 
 FROM 
 sys.fulltext_system_stopwords ssw 
 WHERE 
 ssw.language_id = 1033; 
  

导致查询返回时没有行，即使有一行名为Very Good公司。

我的问题是，如何关闭查询的停用词？或者我会怎样去完全去除它们？

或者我还有另外一种方法去处理这个搜索？

解决方案

如果有其他人绊倒这个问题：

看起来2008年有这样的选择。这对我来说并不明显，因为数据库从2005年开始升级，我不认为这是一个选项。

您需要做的第一件事是设置直到2008年的兼容级别：

  ALTER DATABASE [MyDatabase] SET COMPATIBILITY_LEVEL = 100 
  

然后，通过向导创建全文索引时，您可以忽略索引的停用词

编辑：下面是脚本：/ b>

  ALTER FULLTEXT INDEX ON MyTable SET STOPLIST = OFF 
  

I'm having quite a bit of difficulty finding a good solution for this:

Let's say I have a table of "Company", with a column called "Name". I have a full-text catalog on this column. If a user searched for "Very Good Company", my query would be:

SELECT
    *
FROM
    Company
WHERE
    CONTAINS(Name, '"Very" AND "Good" AND "Company"')

The problem is in this example, the word "Very" shows up in the standard list of stopwords:

SELECT
    ssw.*
FROM
    sys.fulltext_system_stopwords ssw
WHERE
    ssw.language_id = 1033;

Resulting in the query returning with no rows, even though there is a row with the name "Very Good Company".

My question is, how would I go about turning the stopwords off for my query? Or how would I go about removing them entirely?

Or is there another way I should be going about this search?

解决方案

In case anyone else stumbles upon this problem:

It looks like there is an option to do this in 2008; it wasn't apparent to me because the database was upgraded from 2005 where I don't believe this was an option.

The first thing you need to do is set the compatibility level up to 2008:

ALTER DATABASE [MyDatabase] SET COMPATIBILITY_LEVEL = 100

Then, when creating the full-text index through the wizard, there is a step that allows you to ignore stopwords for the index

edit: Here's the script to do it as well:

ALTER FULLTEXT INDEX ON MyTable SET STOPLIST = OFF
