Question

我有简单的 tbl_posts 表，其中有三列（id，name，content）

我为名称和内容列创建了全文索引。当我查询它时：

SELECT  *
FROM    dbo.tbl_posts
WHERE   FREETEXT ( *, 'search word' )

我希望结果订单首先按名称列中的排名然后内容

排序

    CREATE FUNCTION PostFreeTextSearch
    (
     @SearchTerms nvarchar(100)
    )
    RETURNS TABLE 
    AS
    RETURN 
    (
    SELECT
    CASE WHEN fttName.[Key] IS NULL THEN fttContent.[Key] ELSE fttName.[Key] END as id,
    fttName.[RANK] as NameScore,
    fttContent.[RANK] as ContentScore

    FROM 
    FREETEXTTABLE(tbl_Posts, (Name), @SearchTerms) fttName
    FULL OUTER JOIN
    FREETEXTTABLE(tbl_Posts, (Content), @SearchTerms) fttContent ON fttName.[Key] = fttContent.[Key]

    WHERE fttName.RANK > 0 OR fttContent.RANK > 0
    )
    GO
    SELECT * FROM PostFreeTextSearch('sql server')
