我正在尝试找到一种更好的搜索日志表的方法。该表记录在站点上执行的所有搜索，并且可以在单个条件上包含多个过滤器。例如，用户可以在一个搜索中搜索多个县的家庭和多个属性类型。我需要能够运行报告，以查找具有特定属性类型/类型的特定县/县内搜索的用户数。搜索当前记录在下表中：
存储搜索的维度定义：
CREATE TABLE [dbo].[LogSearchDimensions](
[ID] [int] IDENTITY(1,1) NOT NULL,
[VarName] [nvarchar](50) NOT NULL,
[Label] [nvarchar](50) NOT NULL,
[Description] [nvarchar](1024) NOT NULL,
[Created] [datetime] NOT NULL,
CONSTRAINT [PK_LogSearchDimensions] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
示例数据：
ID VarName Label
----------- -------------------------------------------------- --------------------------------------------------
3 City_ID City ID
5 County_ID County ID
7 PageNum Page Number
8 PriceLow Lowest Price
9 PriceHigh Highest Price
10 Region_ID Region ID
11 Site_ID Site ID
14 AcreLow Lowest Acreage
15 AcreHigh Highest Acreage
16 State_ID State ID
17 Style Style
18 SiteStateID Site State ID
19 Distance Distance
20 FIPS FIPS Code
存储主要搜索信息，例如执行搜索时以及执行搜索的人员：
CREATE TABLE [dbo].[LogSearches](
[ID] [numeric](18, 0) IDENTITY(1,1) NOT NULL,
[RecordCount] [int] NOT NULL,
[PageNumber] [int] NOT NULL,
[IPAddress] [varchar](15) NOT NULL,
[Domain] [nvarchar](150) NOT NULL,
[ScriptName] [nvarchar](500) NOT NULL,
[QueryString] [varchar](max) NULL,
[Referer] [nvarchar](1024) NOT NULL,
[SearchString] [nvarchar](max) NOT NULL,
[UserAgent] [nvarchar](2048) NULL,
[Processed] [datetime] NOT NULL,
[Created] [datetime] NOT NULL,
[IntegerIP] [int] NULL,
CONSTRAINT [PK_LogSearches] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
存储每次搜索的尺寸。这可以是单个记录，也可以是50，具体取决于执行的搜索：
CREATE TABLE [dbo].[LogSearchesDimensions](
[ID] [numeric](18, 0) IDENTITY(1,1) NOT NULL,
[LogSearch_ID] [numeric](18, 0) NOT NULL,
[LogSearchDimension_ID] [int] NOT NULL,
[SearchValue] [bigint] NULL,
CONSTRAINT [PK_LogSearchesDimensions] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[LogSearchesDimensions] WITH CHECK ADD CONSTRAINT [FK_LogSearchesDimensions_LogSearchDimensions] FOREIGN KEY([LogSearchDimension_ID])
REFERENCES [dbo].[LogSearchDimensions] ([ID])
ON DELETE CASCADE
GO
ALTER TABLE [dbo].[LogSearchesDimensions] CHECK CONSTRAINT [FK_LogSearchesDimensions_LogSearchDimensions]
GO
ALTER TABLE [dbo].[LogSearchesDimensions] WITH CHECK ADD CONSTRAINT [FK_LogSearchesDimensions_LogSearches] FOREIGN KEY([LogSearch_ID])
REFERENCES [dbo].[LogSearches] ([ID])
ON DELETE CASCADE
GO
ALTER TABLE [dbo].[LogSearchesDimensions] CHECK CONSTRAINT [FK_LogSearchesDimensions_LogSearches]
GO
在LogSearchesDimensions表中，如果用户在一次搜索中搜索了多个县，我可以拥有County_ID（LogSearchDimension_id 5）的多条记录。假设用户在5,6,7,12和15个县进行了搜索。当我运行报告时，这个单一搜索需要显示在所有被搜索的5个县的报告中。如果我运行了一个组合了5和6县的报告，那么它应该只显示一次。
我知道这是很多信息，可能仍然不够，但我希望有人做过类似的事情可以分享一些提示，让这种类型的过滤器以一定的速度工作。
我目前有一个非常复杂的查询，有各种各样的连接，并且有条件尝试找到具有适当匹配数的搜索，但它的表现根本不好。我附上了表格图表来显示关系。alt text http://www.dansshorts.com/searchdiagram.png
我目前正在使用以下方法进行搜索：
CREATE VIEW [dbo].[vwLogSearchesCounty]
AS
SELECT dbo.LogSearches.ID, CAST(FLOOR(CAST(dbo.LogSearches.Created AS FLOAT)) AS DATETIME) AS Created, C.county, C.County_ID, S.state, S.state_ID
FROM dbo.LogSearches WITH (NOLOCK) INNER JOIN
dbo.LogSearchesDimensions AS D WITH (NOLOCK) ON dbo.LogSearches.ID = D.LogSearch_ID AND D.LogSearchDimension_ID = 5 INNER JOIN
propertyControlCenter.dbo.county AS C WITH (NOLOCK) ON C.County_ID = D.SearchValue INNER JOIN
propertyControlCenter.dbo.state AS S WITH (nolock) ON C.state_ID = S.state_ID
DECLARE @LowDate DATETIME, @HighDate DATETIME;
SET @LowDate = '2010-01-01' ;
SET @HighDate = '2010-02-01' ;
SELECT
CONVERT(varchar, Created, 107) AS displayDate
, County , County_ID
, reportCount
FROM (
SELECT
Created
, County_ID , County , reportCount
, DENSE_RANK() OVER(ORDER BY MaxRecords DESC, County) AS theRank
FROM (
SELECT
v.County_ID
, v.Created
, C.county + ' County, ' + S.State_Code AS County
, COUNT(DISTINCT v.ID) AS reportCount
, MAX(COUNT(DISTINCT v.ID)) OVER(PARTITION BY v.County_ID) AS MaxRecords
FROM
vwLogSearchesCounty v (NOLOCK)
INNER JOIN propertyControlCenter.dbo.county C (NOLOCK) ON
v.County_ID = C.County_ID
AND v.Created BETWEEN @LowDate AND @HighDate
AND c.State_ID = 48
INNER JOIN propertyControlCenter.dbo.state S (NOLOCK) ON C.state_ID = S.state_ID
INNER JOIN LogSearchesDimensions D (NOLOCK) ON v.ID = D.LogSearch_ID AND D.LogSearchDimension_ID IN (8, 9, 14, 15, 17)
WHERE
1 = 0
OR (
D.LogSearchDimension_ID = 17
AND D.SearchValue IN (2,5,6 )
)
GROUP BY
v.Created
, v.County_ID
, C.County
, S.State_Code
HAVING COUNT(v.ID) >= 3 ) d
GROUP BY
Created
, County
, County_ID
, reportCount
, MaxRecords )
ranking
WHERE theRank <= 5
ORDER BY theRank, County_ID, Created
当前记录数： LogSearches：8,970,000 LogSearchesDimensions：37,630,000
上述查询需要24秒才能运行（对于我们的目的而言太长）并返回以下数据：
