如何使用PowerShell重建Windows搜索索引？

Question

因为我们没有找到任何解决方案来发展我们不断增长的Windows搜索数据库（甚至没有微软的帮助），我们决定在SCOM定期重建数据库时，他们达到了一个特定的限制。这涉及到Windows Server 2012 R2。

我为此需要一个PowerShell脚本，该脚本调用属于ISearchCatalogManager接口的Reset或Reindex方法。

到目前为止，我想出了以下内容：

# Load DLL containing classes & interfaces 
Add-Type -path "C:\Temp\SearchIndex\Microsoft.Search.Interop.dll" 

# Create new ISearchManager object 
$sm = New-Object Microsoft.Search.Interop.ISearchManager 

# should return ISearchCatalogManager object 
$catalog = $sm.GetCatalog("SystemIndex") 

# Call the method 
$catalog.Reindex() 

然而，这会引发以下异常：

New-Object : A constructor was not found. Cannot find an appropriate constructor for type Microsoft.Search.Interop.ISearchManager. 
At C:\Users\myuser\Desktop\test.ps1:8 char:6 
+ $sm = New-Object Microsoft.Search.Interop.ISearchManager 
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
    + CategoryInfo   : ObjectNotFound: (:) [New-Object], PSArgumentException 
    + FullyQualifiedErrorId : CannotFindAppropriateCtor,Microsoft.PowerShell.Commands.NewObjectCommand 

我在做什么错在这里？

我发现我使用的是Microsoft.Search.Interop.dll的过期版本。

这是我如何解决它：

首先下载Windows Search 3.x SDK来自微软。忽略有关系统要求的部分。所需的DLL也可以在2012 R2上使用（很可能在8.1上）。然后使用下面的PowerShell代码重置搜索索引。

# Load DLL containing classes & interfaces 
Add-Type -path "C:\Temp\SearchIndexSdk\Microsoft.Search.Interop.dll" 

# Provides methods for controlling the Search service. This 
# interface manages settings and objects that affect the search engine 
# across catalogs. 
# 
# https://msdn.microsoft.com/en-us/library/bb231485(v=vs.85).aspx 
$sm = New-Object Microsoft.Search.Interop.CSearchManagerClass 

# Retrieves a catalog by name and creates a new ISearchCatalogManager 
# object for that catalog. 
$catalog = $sm.GetCatalog("SystemIndex") 

# Resets the underlying catalog by rebuilding the databases 
# and performing a full indexing. 
#

$catalog.Reset()
