我有3张桌子,

1. tblBook(BookID, ISBN, Title, Summary)
2. tblAuthor(AuthorID, FullName)
3. tblBookAuthor(BookAuthorID, BookID, AuthorID)

tblBookAuthor 允许一本书有多个作者,作者可能已经写了任意数量的书.

我正在使用全文搜索来搜索基于单词的排名:

SET @Word = 'FORMSOF(INFLECTIONAL, "' + @Word + '")'

SELECT 
  COALESCE(ISBNResults.[KEY], TitleResults.[KEY], SummaryResults.[KEY]) AS [KEY],
  ISNULL(ISBNResults.Rank, 0) * 3 +
  ISNULL(TitleResults.Rank, 0) * 2 +
  ISNULL(SummaryResults.Rank, 0) AS Rank
FROM
  CONTAINSTABLE(tblBook, ISBN, @Word, LANGUAGE 'English') AS ISBNResults
  FULL OUTER JOIN 
    CONTAINSTABLE(tblBook, Title, @Word, LANGUAGE 'English') AS TitleResults 
    ON ISBNResults.[KEY] = TitleResults.[KEY]
  FULL OUTER JOIN
    CONTAINSTABLE(tblBook, Summary, @Word, LANGUAGE 'English') AS SummaryResults 
    ON ISBNResults.[KEY] = SummaryResults.[KEY] 

上面的代码适用于搜索tblBook …
