ASP.NET/sql 全文搜索

Question

我正在使用以下查询来进行 sql server 的全文搜索。

    DECLARE @MyTable TABLE (Id int identity(1,1), Searched varchar(200))
DECLARE @Keys    TABLE (Word varchar(200), WordId int identity(1,1))

INSERT INTO @MyTable VALUES ('Mother Father Daughter Son')
INSERT INTO @MyTable VALUES ('Mother Daughter Son')
INSERT INTO @MyTable VALUES ('Mother Son')
INSERT INTO @MyTable VALUES ('Daughter Son')
INSERT INTO @MyTable VALUES ('Mother Father Son')
INSERT INTO @MyTable VALUES ('Son Daughter Father')
INSERT INTO @MyTable VALUES ('Mother bun')
INSERT INTO @MyTable VALUES ('Other Word')


INSERT INTO @Keys VALUES ('Mother')
INSERT INTO @Keys VALUES ('Father')
INSERT INTO @Keys VALUES ('Son')
INSERT INTO @Keys VALUES ('Daughter')

DECLARE @nAllWords int
SELECT @nAllWords = COUNT(*) FROM @Keys

SELECT MyTable.*
FROM @MyTable MyTable
INNER JOIN (SELECT MyTable.Id
                   FROM @MyTable MyTable
            INNER JOIN @Keys KeyWords ON ' ' + MyTable.Searched + ' ' LIKE '% ' + KeyWords.Word  + ' %'
            GROUP BY MyTable.Id
            HAVING COUNT(Distinct(KeyWords.Word)) = @nAllWords) Tbl1 ON MyTable.Id = Tbl1.Id

但是上面的代码只返回一个以下的单个记录。

Mother Father Daughter Son

我需要完整的 4 个单词（母亲父亲女儿儿子），下一个任何 3 个单词（母亲女儿儿子），下一个任何 2 和下一个 1 所以我的结果像

Mother Father Daughter Son
Mother Daughter Son
Mother Father Son
      :
      :

Mother bun

请就多列向我提出建议，我现在正在尝试一列。一旦我得到这个，接下来我将尝试多列。

如果您从查询中删除以下代码，它将给出所需的结果！

HAVING COUNT(Distinct(KeyWords.Word)) = @nAllWords
