【问题描述】:
我刚刚设法启用全文搜索,以便更轻松地在我的系统中搜索产品。但是,我使用的是由其他人构建的 sp,它没有为“值班电话”返回任何结果。实际上,我正在搜索系统中的产品“使命召唤”。如果我输入“使命召唤”,它确实会返回结果,但删除一个单词并翻转剩余的单词不会给出结果。代码如下:
USE [storeboard]
GO
/****** Object: StoredProcedure [sbuser].[sp_ProductSearch] Script Date: 08/26/2010 05:57:20 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROC [sbuser].[sp_ProductSearch]
@StoreItemID bigint = null,
@StoreMemberID bigint = null,
@ProductName varchar(50) = null,
@ProductDesc varchar(1000) = null,
@ItemPrice float = null,
@Active bit = null,
@Deleted bit = null,
@CreateDate datetime = null,
@ShipWeight float = null,
@TaxExempt bit = null,
@ShipCost float = null,
@Keywords varchar(1000) = null,
@PG int = 1,
@ROWCT numeric(18,2) = 1,
@COLCT numeric(18,2) = 1,
@MODE varchar(50),
@StoreItemCatID bigint = null,
@SearchStr varchar(100) = null
AS
IF @MODE = 'S1'
BEGIN
SELECT
StoreItemID,
ProductName,
ItemPrice,
PG,
MAXPG,
TOTALRECS,
CoverImg,
StoreItemCatID,
Active
FROM sbuser.tf_ProductSearch(@PG,@ROWCT,@COLCT,@StoreItemCatID,@SearchStr)
END
代码指的是 tf_productSearch 是这样的:
USE [storeboard]
GO
/****** Object: UserDefinedFunction [sbuser].[tf_ProductSearch] Script Date: 08/26/2010 05:46:36 ******/

AND a.Deleted = 0
AND a.Active = 1
OR a.StoreItemCatID IN (SELECT StoreItemCatID FROM StoreItemCat WHERE ParentID = @StoreItemCatID)
AND FREETEXT (a.ProductName, @SearchStr)
AND a.Deleted = 0
AND a.Active = 1
ORDER BY a.ProductName
END
SELECT @TOTALRECS = MAX(TMPID) FROM @TMP1
SELECT @MAXPG = @TOTALRECS / @SIZE
SET @TOTALRECS_REMAINDER = @TOTALRECS % @SIZE
SET @MAXPG_INT = CAST(@MAXPG AS INT)
SET @TOTALRECS_INT = CAST(@TOTALRECS AS INT)

WHERE (TmpID >= @Start) AND (TmpID <= @END)
RETURN
END
在经典 ASP 网页中调用,代码如下:
Dim ProductCat
Dim paryProducts
Dim ProdMaxPG
Dim pstrProductList
Const C_PRODUCTS_FE_PRODUCTROWCOUNT = 4
Const C_PRODUCTS_FE_PRODUCTCOLCOUNT = 5
SearchStr = "duty call"
StoreItemCatID = ""
cData.SQL = "sp_ProductSearch " _
& cData.ProcFld("MODE","S1",2,True) _
& cData.ProcFld("PG",PG,0,True) _
& cData.ProcFld("ROWCT",C_PRODUCTS_FE_PRODUCTROWCOUNT,0,True) _
& cData.ProcFld("COLCT",C_PRODUCTS_FE_PRODUCTCOLCOUNT,0,True) _
& cData.ProcFld("SearchStr",SearchStr,2,True) _
& cData.ProcFld("StoreItemCatID",StoreItemCatID,0,False)
paryProducts = cData.RSArray()
但是,这些脚本不返回任何结果。但是,直接在sql-server的查询窗口中输入以下代码:
USE storeboard
GO
DECLARE @SearchStr varchar(50)
SET @SearchStr = 'duty call';
SELECT
a.StoreItemID,
a.ProductName,
a.ProductDesc,
a.ItemPrice,
a.Active,
a.CreateDate,
a.ShipWeight,
a.TaxExempt,
a.ShipCost,
a.Keywords,
a.StoreItemCatID
FROM sbuser.StoreItem a
WHERE FREETEXT (a.ProductName, @SearchStr)
AND a.Deleted = 0
AND a.Active = 1
ORDER BY a.ProductName
确实返回结果。我在这里不合群,想知道你们中的一位经验丰富的程序员是否会在这里看到明显错误的地方。如果你们能提供任何帮助,我们将不胜感激。
非常感谢,
保罗
【问题讨论】:
-
你能不能试着把它剪成一个更小的例子 - 这里有很多东西要通读,我认为很多人不会坚持下去。
-
我不确定是否可以缩小它的大小,因为所有这些代码都是相关的。
