Set-SPEnterpriseSearchMetadataMapping
为 Search Service 应用程序设置托管属性映射的属性。
语法
Set-SPEnterpriseSearchMetadataMapping
[-Identity] <MappingPipeBind>
[-SearchApplication <SearchServiceApplicationPipeBind>]
[-AssignmentCollection <SPAssignmentCollection>]
[-Confirm]
[-CrawledProperty <CrawledPropertyPipeBind>]
[-ManagedProperty <ManagedPropertyPipeBind>]
[-SiteCollection <Guid>]
[-Tenant <Guid>]
[-WhatIf]
[<CommonParameters>] 说明
此 cmdlet 可更新托管属性映射的属性。 SPEnterpriseSearchMetadataMapping 表示企业级搜索元数据属性架构中的一个托管属性与一个或多个已爬网属性之间的映射。

示例
------------------示例------------------
$ssa = Get-SPEnterpriseSearchServiceApplication
## get the crawl property to set to, in this case a new property is created
$cat = Get-SPEnterpriseSearchMetadataCategory -SearchApplication $ssa -Identity People
$cp = Get-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $ssa -Category $cat -Limit 1
$ncp = New-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $ssa -Name "MyNewCrawlProp" -PropSet $cp.PropSet -Category $cp.CategoryName -IsNameEnum $false -VariantType $cp.VariantType -IsMappedToContents $true
## get the mapping to replace
$mycp = Get-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $ssa -Name MyCrawlProp
$map = Get-SPEnterpriseSearchMetadataMapping -SearchApplication $ssa -ManagedProperty $mp -CrawledProperty $mycp
## set the new crawl property to map to for this mapping
Set-SPEnterpriseSearchMetadataMapping -Identity $map -SearchApplication $ssa -CrawledProperty $ncp此示例更新托管属性 UserName 和已爬网属性 MyCrawlProp 之间的现有映射， (请参阅 New-SPEnterpriseSearchMetadataMapping 默认搜索服务应用程序的) 。
已爬网属性将由名为 MyNewCrawlProp 的新已爬网属性取代。
参数
-AssignmentCollection
管理对象以便正确进行处理。 使用 SPWeb 或 SPSite 等对象可能会耗用大量内存，而且在 Windows PowerShell 脚本中使用这些对象需要正确管理内存。 通过使用 SPAssignment 对象，可以将对象分配给变量，然后在不需要这些对象时对它们进行处理，以释放内存。 在使用 SPWeb、SPSite 或 SPSiteAdministration 对象时，如果不使用分配集合或 Global 参数，则会自动处理这些对象。
使用全局参数时，所有对象均包含在全局存储中。
如果未立即使用对象，或未通过使用 Stop-SPAssignment 命令来处理对象，则可能会发生内存不足的情况。
