告诉我SQL Server全文搜索器很疯狂,不是我

Question

我有一些客户具有用户正在搜索的特定地址:

123通用方式

数据库中有5行匹配:

ResidentialAddress1
=============================
123 GENERIC WAY
123 GENERIC WAY
123 GENERIC WAY
123 GENERIC WAY
123 GENERIC WAY

---

我运行FT查询来查找这些行.我将向您展示每一步,因为我为搜索添加了更多条件:

SELECT ResidentialAddress1 FROM Patrons
WHERE CONTAINS(Patrons.ResidentialAddress1, '"123*"')

ResidentialAddress1
=========================
123 MAPLE STREET
12345 TEST
123 MINE STREET
123 GENERIC WAY
123 FAKE STREET
...

(30 row(s) affected)

好的,到目前为止一直很好,现在添加" 通用 " 一词:

SELECT ResidentialAddress1 FROM Patrons
WHERE  CONTAINS(Patrons.ResidentialAddress1, '"123*"')
AND CONTAINS(Patrons.ResidentialAddress1, '"generic*"')

ResidentialAddress1
=============================
123 GENERIC WAY
123 GENERIC WAY
123 GENERIC WAY
123 GENERIC WAY
123 GENERIC WAY

(5 row(s) affected)

优秀.现在我将添加用户想要确保存在的最终关键字:

SELECT ResidentialAddress1 FROM Patrons
WHERE  CONTAINS(Patrons.ResidentialAddress1, '"123*"')
AND CONTAINS(Patrons.ResidentialAddress1, '"generic*"')
AND CONTAINS(Patrons.ResidentialAddress1, '"way*"')


ResidentialAddress1            
------------------------------ 

(0 row(s) affected)

咦？没有行？如果我只查询"方式*"怎么办:

SELECT ResidentialAddress1 FROM Patrons
WHERE CONTAINS(Patrons.ResidentialAddress1, '"way*"')

ResidentialAddress1            
------------------------------ 

(0 row(s) affected)

起初我认为也许是因为它*,并且它要求根way在它之后有更多的字符.但事实并非如此:

• 正在搜索"123*"匹配"123"
• 搜索"generic*"匹配"generic"
• 在线书籍说,星号匹配零个,一个或多个字符

如果我删除了*刚才的s&g 怎么办？

SELECT ResidentialAddress1 FROM Patrons
WHERE CONTAINS(Patrons.ResidentialAddress1, '"way"')

Server: Msg 7619, Level 16, State 1, Line 1
A clause of the query contained only ignored words. 

---

因此,人们可能会认为你只是甚至不允许搜索的way,单独或作为一个根.但这也不是真的:

SELECT * FROM Patrons
WHERE CONTAINS(Patrons.*, '"way*"')

AccountNumber FirstName Lastname
------------- --------- --------
33589         JOHN      WAYNE                    

---

总而言之,用户正在搜索包含所有单词的行:

123通用方式

我正确地将其转化为WHERE条款:

SELECT * FROM Patrons
WHERE CONTAINS(Patrons.*, '"123*"')
AND CONTAINS(Patrons.*, '"generic*"')
AND CONTAINS(Patrons.*, '"way*"')

它不返回任何行.告诉我这不会起作用,这不是我的错,而且SQL Server很疯狂.

注意:我已经清空FT指数并重建它.

更新一

SELECT Lastname, ResidentialAddress1 FROM Patrons
WHERE CONTAINS(Patrons.*, '"gen*"')

Lastname                  ResidentialAddress1            
------------------------- ------------------------------ 
SAVE                      123 GENERIC WAY
Genders                   
SAVE                      123 GENERIC WAY
Patron                    123 GENERIC WAY
SAVE                      123 GENERIC WAY
SAVE                      234 GENERIC WAY
SAVE                      123 GENERIC WAY

(7 row(s) affected)

更新二

假装用户输入:

123通用wa

SELECT ResidentialAddress1 FROM Patrons
WHERE  CONTAINS(Patrons.ResidentialAddress1, '"123*"')
AND CONTAINS(Patrons.ResidentialAddress1, '"generic*"')
AND CONTAINS(Patrons.ResidentialAddress1, '"wa*"')

ResidentialAddress1            
------------------------------ 

(0 row(s) affected)

真正的问题是用户输入完全有效的东西,他们希望看到任何人都期望看到的东西.

更新四

查询不能写为

CONTAINS(Patrons.*, 'words...')

由于FT指数中没有逻辑或物理覆盖的项目.例如,用户查询:

6/4/2010 ian boyd 619

提供四个关键字:

• 2010年6月4日
• 伊恩
• 博伊德
• 619

这意味着他们希望所有条件都成立,伪代码为:

WHERE 6/4/2010 is in the row
AND ian is in the row
AND boyd is in the row
AND 619 is in the row

哪个被翻译成部分查询:

WHERE --Keyword 1: 6/4/2010
(
   ((ChangedDate >= '20100604') AND (ChangedDate < '20100605'))
   OR 
   ((LastTransactionDate >= '20100604') AND (LastTransactionDate < '20100605'))
   OR 
   (CONTAINS(Patrons.*, '"6/4/2010*"')
)
AND --Keyword 2: ian
(
    CONTAINS(Patrons.*, '"ian*"')
)
AND --Keyword 3: boyd
(
    CONTAINS(Patrons.*, '"boyd*"')
)
AND --Keyword 4: 619
(
    (AccountNumber IN (SELECT CAST(619 AS bigint)))
    OR
    (CONTAINS(Patrons.*, '"619*"'))
)

其中一位回答者正在查看原始问题中提出的简化示例; 不是现实世界.说有多个条款是不正确的AND.

Answer 1

该消息告诉您"方式"是一个停用词,这意味着它被忽略而没有索引.这就是为什么你可以找到"wayne"而不是"way"的原因.

所以,不,这不是疯了,你也不是.这只是一个简单的误解.
