Deletes a metadata mapping from a managed property.

Remove-SPEnterpriseSearchMetadataMapping [-Identity] <MappingPipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-SearchApplication <SearchServiceApplicationPipeBind>] [-WhatIf [<SwitchParameter>]]


Parameter Required Type Description




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.




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.

note Note:

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.




Prompts you for confirmation before executing the command. For more information, type the following command: get-help about_commonparameters




Specifies the search application that contains the managed property collection.

The type must be a valid search application name, for example, SearchApp1, or an instance of a valid SearchServiceApplication object.




Displays a message that describes the effect of the command instead of executing the command. For more information, type the following command: get-help about_commonparameters

Detailed 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.

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

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.
