Question

我要进行查询检索人近语法。当我搜索第二个单词中包含字母N的任何文本时，结果始终为空。

我有两个人在桌子上注册了里卡多，分别是“里卡多·莫瓦”和“里卡多·诺瓦”。如果搜索“里卡多NEAR‘MOVA *’”这是确定的，而不是“里卡多NEAR‘新星*’

4条记录（里卡多·诺瓦，里卡多·诺瓦伊斯，里卡多·诺沃，里卡多·纳内斯）
查询'Ricardo NEAR'N *'
结果仅显示“ Ricardo Novais”和“ Ricardo Nunes”。

表格：

CREATE TABLE [dbo].[EntitySearch](
    [IdEntity] [int] NOT NULL,
    [Name] [nvarchar](max) NULL,
    [Accessibility] [bit] NOT NULL,
    [Document] [nvarchar](max) NULL,
    [Email] [nvarchar](max) NULL,
    [Phone] [nvarchar](max) NULL,
    [Phone2] [nvarchar](max) NULL,
    [Birthdate] [datetime] NULL,
    [Gender] [int] NULL,
    [IsAct] [bit] NOT NULL,
    [Discriminator] [int] NOT NULL,
 CONSTRAINT [PK_dbo.EntitySearch] PRIMARY KEY CLUSTERED 
(
    [IdEntity] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY =     OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

CREATE FULLTEXT CATALOG main_catalog;

展开索引

CREATE FULLTEXT INDEX ON dbo.EntitySearch 
        (       [Name] 
            Language[Brazilian],  
                [Document]
            Language[Brazilian],
                [Email]
            Language[Brazilian], 
                [Phone]
            Language[Brazilian],
                [Phone2]
            Language[Brazilian] )  
KEY INDEX [PK_dbo.EntitySearch] ON main_catalog;

查询：

SELECT top 10
    FT_TBL.[IdEntity]
    ,FT_TBL.[Name]
    ,FT_TBL.[Accessibility]
    ,FT_TBL.[Document]
    ,FT_TBL.[Email]
    ,FT_TBL.[Phone]
    ,FT_TBL.[Phone2]
    ,FT_TBL.[Birthdate]
    ,FT_TBL.[Gender]
    ,FT_TBL.[IsAct]
    ,FT_TBL.[Discriminator]
    FROM [EntitySearch] AS FT_TBL INNER JOIN  
    CONTAINSTABLE ([EntitySearch], [Name], 'Ricardo NEAR "Nova*"' ) AS KEY_TBL  
    ON FT_TBL.[IdEntity] = KEY_TBL.[KEY]  
    WHERE
        FT_TBL.[IsAct] = 1 
    and FT_TBL.[Discriminator] = 2
    and KEY_TBL.RANK > 10  
    ORDER BY KEY_TBL.RANK DESC, FT_TBL.[Name]

我希望显示1条记录，但没有显示。谢谢！

编辑：替代方法

我放弃了，并使用葡萄牙语将其改写为全文索引。问题已经解决了，所以我猜“ bug”是在巴西语言上作为索引。

这不是错误。

每种语言都有您自己的自停单词列表，这意味着某些单词与索引搜索无关。

https://docs.microsoft.com/en-us/sql/relational-databases/search/configure-and-manage-stopwords-and-stoplists-for-full-text-search?view=sql-server-2017

SELECT * 
FROM sys.fulltext_system_stopwords 
WHERE language_id = 1046 --Brazilian language ID

因此，以我为例，我做了一种算法，可以在发送之前更正搜索查询。

SQL服务器CONTAINSTABLE不返回与字结果，与“N”
