为什么SQL Server全文搜索返回一个数字而不是其他数字

Question

我与Columns AgreementID int和BaseAgreementNumber NVARCHAR（20）签订了一份协议，其中包含以下数据。

+-------------+----------------------+
| AgreementID | BaseAgreementNumber  |
+-------------+----------------------+
|      181672 |      365141240514359 |
|      179078 |                15943 |
+-------------+----------------------+

记录ID 189072未显示在结果中，而记录ID为179078。

有人可以解释为什么会这样吗？

是使用以下脚本创建的表

CREATE TABLE [dbo].[Agreement](
[AgreementID] [int] IDENTITY(1,1) NOT NULL,
[BaseAgreementNumber] [nvarchar](20) NULL,

 CONSTRAINT [PK_Agreement] PRIMARY KEY CLUSTERED 
(
  [AgreementID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 90) ON [PRIMARY]
) ON [PRIMARY]

全文目录创建如下

CREATE FULLTEXT INDEX ON [dbo].[Agreement] KEY INDEX [PK_Agreement] ON ([AIMIEFTS]) WITH (CHANGE_TRACKING AUTO)
GO

ALTER FULLTEXT INDEX ON [dbo].[Agreement] ADD ([BaseAgreementNumber] LANGUAGE [Neutral])
GO

以下查询不返回任何行

select * from Agreement where CONTAINS(BaseAgreementNumber, '365141240514359')

但是这个查询会返回行。

select * from Agreement where CONTAINS(BaseAgreementNumber, '15943')
