Description

This cmdlet deletes mappings from a managed property. A metadata mapping is the mapping between a managed property and one or more crawled properties in the enterprise search metadata property schema.

Examples

------------------EXAMPLE------------------

PS C:\>$searchapp = Get-SPEnterpriseSearchServiceApplication
PS C:\>$cat = Get-SPEnterpriseSearchMetadataCategory -SearchApplication $searchapp -Identity People 
PS C:\>$cp = Get-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -Category $cat -Limit 1 
PS C:\>$mycp = New-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -Name "MyCrawlProp" -PropSet $cp.PropSet -Category $cp.CategoryName -IsNameEnum $false -VariantType $cp.VariantType
PS C:\>$mp = Get-SPEnterpriseSearchMetadataManagedProperty -SearchApplication $searchapp -Identity UserName
PS C:\>New-SPEnterpriseSearchMetadataMapping -SearchApplication $searchapp -ManagedProperty $mp -CrawledProperty $mycp
# Retrieve the new mapping
PS C:\>$map = Get-SPEnterpriseSearchMetadataMapping -SearchApplication $searchapp -ManagedProperty $mp -CrawledProperty $mycp
PS C:\>Remove-SPEnterpriseSearchMetadataMapping -Identity $map -confirm:$false

This example removes an existing mapping between the managed property UserName and the crawled property MyCrawlProp (see Set-SPEnterpriseSearchMetadataMapping) for the default search service application.

Required Parameters

-Identity

Specifies the metadata mapping to delete.

The type must be a valid URL, in the form http://server_name, or an instance of a valid Mapping object.

Type:MappingPipeBind
Position:1
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False
Applies to:SharePoint Server 2010, SharePoint Server 2013, SharePoint Server 2016

Optional Parameters

-AssignmentCollection

Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.

Type:SPAssignmentCollection

Default value:None
Accept pipeline input:True (ByValue)
