FreeTextTable不返回任何记录

我有一个平面表来执行全文搜索，即使是最简单的搜索也无法正常工作。我尝试过很多东西，但结果相同。令人惊讶的是，类似的全文搜索适用于同一数据库中的其他表。

下面是我的表结构，我还添加了全文索引详细信息以供快速参考。 Table Structure and Full Text Options

以下是我的查询的搜索结果，我已经尝试了多个没有运气的东西，只有当我从列中提供精确值时，查询才有效。 Search Result 即使我在查询中使用一列即Fname，搜索结果也是相同的。

我可能会遗漏一些基本的东西，但我不确定那是什么东西。下面是它的创建表脚本。

更新1： 因此，我进一步深入研究，发现类似于我的问题。

因此，如果正确理解这些URL，那么FreeTextTable不会对一个单词起作用，这肯定不正确，因为我在另一个表上使用一个单词查询并且它工作得很好。 One word FTT query

答案 0 :(得分：0)

您正在尝试执行FreeTextTable不支持的子字符串匹配。相反，请将ContainsTable与通配符一起使用。

select * from ContainsTable(SampleTable, ([FName],[IName]), 'clima*')

此搜索将匹配以下字符串：

  • ＆＃34; climate.c＆＃34;
  • ＆＃34; climate.c blah blah＆＃34;
  • ＆＃34; blah blah climate.c＆＃34;
  • ＆＃34; blah blah climate.c blah blah＆＃34;
  • ＆＃34;バ＆＃34;
  • ＆＃34; blah blah clima＆＃34;

但赢了＆＃t> 匹配：

  • ＆＃34; xxclimate＆＃34;

FYI FreeTextTable用于自然语言类型搜索 - 同义词，单数/复数形式，共轭匹配，搜索中只需要1个术语即可匹配。 ContainsTable匹配确切的单词（没有同义词等），允许布尔运算符（AND，OR，NOT），支持通配符（*，？），并且可以执行邻近搜索（word2的N个单词中的word1）。 / p>
