CONTAINSTABLE 查询不识别小词

Question

我正在使用CONTAINSTABLE 搜索两个表格列。一旦搜索包含像 'the' 'for' 'a' 这样的小词，即使它们实际出现在列中，搜索也不会返回任何结果。

快速示例。正在搜索的列包含文本。 '系统需要升级'

以下 SQL 返回 0 行

SELECT     * FROM Incident WHERE (TicketNumber IN (
SELECT TicketNumber FROM         [Action] FT_TBL INNER JOIN
CONTAINSTABLE(Action, Text, '"system" AND "needs" AND "to" AND "upgraded" AND NOT "Search Summary"') KEY_TBL ON FT_TBL.ID = KEY_TBL.[KEY]
UNION
SELECT TicketNumber FROM [Incident] FT_TBL INNER JOIN
CONTAINSTABLE(Incident, Subject, '"system" AND "needs" AND "to" AND "upgraded"') AS KEY_TBL ON FT_TBL.TicketNumber = KEY_TBL.[KEY]))

一旦 'to' 被省略，它就可以正常工作：

SELECT     * FROM Incident WHERE (TicketNumber IN (
SELECT TicketNumber FROM         [Action] FT_TBL INNER JOIN
CONTAINSTABLE(Action, Text, '"system" AND "needs" AND "upgraded" AND NOT "Search Summary"') KEY_TBL ON FT_TBL.ID = KEY_TBL.[KEY]
UNION
SELECT TicketNumber FROM [Incident] FT_TBL INNER JOIN
CONTAINSTABLE(Incident, Subject, '"system" AND "needs" AND "upgraded"') AS KEY_TBL ON FT_TBL.TicketNumber = KEY_TBL.[KEY]))

CONTAINSTABLE 如何与这些较小的词一起使用，或者应该完全省略它们？如果这些较小的词在搜索中实际上是有意义的，那么它们如何被包含在搜索中？

Answer 1

这些不是“小词”，它们是停用词表上的常用词。它们被忽略了。

请参阅 BOL 上的 Stopwords and Stoplists。

Answer 2

请参阅the end of my answer，了解如何创建和使用从空列表开始的自定义全文停止列表。我检查了一个空的，你的查询适用于“to”、“be”、“the”、“for”等。

更新：

SQL Server 2005 应该有 MSSQL\FTData\noiseENG.txt。
我建议查看question "Noise Words in Sql Server 2005 Full Text Search"的答案
