目前，我正在尝试从SQLServer2008R2实例(也在SQLServer 2012上进行了测试)查询Windows搜索服务。Windows搜索被公开为OLE DB数据源，为我提供了几个查询搜索索引的选项。在SQLServer中配置新的链接服务器时，ManagementStudio允许我选择MicrosoftOLE DB提供程序进行搜索，这意味着我应该能够从SQLServer连接到它。然而，要让它启动并运行起来却是一个挑战。下面你会发现我偶然发现的错误信息。
OLE DB provider "Search.CollatorDSO" for linked server "TESTSERVER" returned message "Command was not prepared.".
Msg 7399, Level 16, State 1, Line 2
The OLE DB provider "Search.CollatorDSO" for linked server "TESTSERVER" reported an error. Command was not prepared.
Msg 7350, Level 16, State 2, Line 2
Cannot get the column information from OLE DB provider "Search.CollatorDSO" for linked server "TESTSERVER".
，我需要搜索网络驱动器，这能使用共享Windows库吗？
我知道在过去的几年里，越来越多的人一直在努力解决这个问题。我想知道是否有人能把它启动并运行，或者能给我指明正确的方向。
OLEDB工程
普通ADO/OLEDB组件可以使用连接字符串查询Windows搜索服务：
provider=Search.CollatorDSO.1;EXTENDED PROPERTIES="Application=Windows"
还有一个示例查询：
SELECT TOP 100000 "System.ItemName",
"System.ItemNameDisplay",
"System.ItemType",
"System.ItemTypeText",
"System.Search.EntryID",
"System.Search.GatherTime",
"System.Search.HitCount",
"System.Search.Store",
"System.ItemUrl",
"System.Filename",
"System.FileExtension",
"System.ItemFolderPathDisplay",
"System.ItemPathDisplay",
"System.DateModified",
"System.ContentType",
"System.ApplicationName",
"System.KindText",
"System.ParsingName",
"System.SFGAOFlags",
"System.Size",
"System.ThumbnailCacheId"
FROM "SystemIndex"
WHERE CONTAINS(*,'"Contoso*"',1033)您可以尝试运行以下命令，在SQLServer管理Studio中直接在SQLServer上尝试查询：
SELECT *
FROM OPENROWSET(
'Search.CollatorDSO',
'Application=Windows',
'SELECT TOP 100 "System.ItemName", "System.FileName" FROM SystemIndex');这就产生了错误：
OLE DB provider "Search.CollatorDSO" for linked server "(null)" returned message "Command was not prepared.". Msg 7399, Level 16, State 1, Line 1 The OLE DB provider "Search.CollatorDSO" for linked server "(null)" reported an error. Command was not prepared. Msg 7350, Level 16, State 2, Line 1 Cannot get the column information from OLE DB provider "Search.CollatorDSO" for linked server "(null)".
