我试图在我的 SQL Server 2008 上重现您所谓的“错误”（请参阅下面的代码）。结果，它完全按照您的预期工作。我很惊讶你一开始没有提供完整的代码。
更新：将完整索引的语言更改为葡萄牙语并收到相同的结果。它显示“类似错误的行为”。
更新：
为什么会这样？
MS 在 SQL Server 2008 中引入了新的分词器，葡萄牙语就是其中之一。
我的意思是，SQL 在搜索单词时应该忽略换行符
才不是。我不认为这是全文引擎的默认行为。至少不能接受。
更新：看起来这种行为可以在所有新的断路器中看到。

由 MS 决定这是否可以接受。不过，您可以通过支持服务提交票证。
如果我的用户在我的表格上插入带有换行符的行会发生什么
（这很常见，因为他们可以写任何他们想要的东西，因为
该字段是备注字段）？
所见即所得
有什么办法可以改正吗？
也许您需要上传自己的断字系统或降级到 SQL Server 2005。
总之祝你好运！
