查找Sharepoint 2010中的所有重複文檔

當我們在我們的SharePoint實例上執行一些搜索時，我們會在搜索結果中看到幾個文件中的「查看重複」鏈接。查找Sharepoint 2010中的所有重複文檔

有沒有辦法報告所有這些重複？

我見過有這個SQL這裏根據自己的MD5哈希查找重複：http://social.technet.microsoft.com/forums/en-US/sharepointsearch/thread/8a8b25d9-a3ac-45df-86de-2a3a7838a534和我已經糾正了SQL爲SharePoint 2010的兼容性這裏：

-- Step1 : get all files with short names, md5 signatures, and size 
SELECT md5 , 
     RIGHT(DisplayURL, CHARINDEX('/', REVERSE(DisplayURL)) - 1) AS ShortFileName , 
     DisplayURL AS Url , 
     llVal/1024 AS FileSizeKb 
INTO #listingFilesMd5Size 
FROM SearchServiceApplication_CrawlStore.dbo.MSSCrawlURL y 
     INNER JOIN SearchServiceApplication_PropertyStore.dbo.MSSDocProps dp ON (y.DocID = dp.DocID) 
WHERE dp.pid = 58 -- File size 
     AND llVal > 1024 * 10 -- 10 Kb minimum in size 
     AND md5 <> 0 
     AND CHARINDEX('/', REVERSE(DisplayURL)) > 1 

-- Step 2: Filter duplicated items 

SELECT COUNT(*) AS NbDuplicates , 
     md5 , 
     ShortFileName , 
     FileSizeKb 
INTO #duplicates 
FROM #listingFilesMd5Size 
GROUP BY md5 , 
     ShortFileName , 
     FileSizeKb 
HAVING COUNT(*) > 1 
ORDER BY COUNT(*) DESC 

DROP TABLE #listingFilesMd5Size 

-- Step3 : show the report with search URLs 

SELECT *, 
     NbDuplicates * FileSizeKb AS TotalSpaceKb , 
     'http://srv-moss/SearchCenter/Pages/results.aspx?k=' + ShortFileName AS SearchUrl 
FROM #duplicates 
--ORDER BY NbDuplicates * FileSizeKb DESC 

DROP TABLE #duplicates

但這僅匹配確切的重複，而我對SharePoint認爲基於搜索結果中的「查看重複」鏈接的副本感興趣。

我已經看到有託管屬性「DuplicateHash」但這沒有記錄在任何地方，我找不到通過對象模型訪問它的方式。

感謝
