Remove-SPEnterpriseSearchMetadataMapping

 

Applies to: SharePoint Server 2010

Topic Last Modified: 2010-02-11

Deletes a metadata mapping from a managed property.

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

The Remove-SPEnterpriseSearchMetadataMapping cmdlet deletes unused or unwanted 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.

 

Parameter Required Type Description

Identity

Required

Microsoft.Office.Server.Search.Cmdlet.MappingPipeBind

Specifies the metadata mapping to delete.

A valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid URL, in the form http://server_name; or an instance of a valid CrawlMapping object.

AssignmentCollection

Optional

Microsoft.SharePoint.PowerShell.SPAssignmentCollection

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.

noteNote
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.

Confirm

Optional

System.Management.Automation.SwitchParameter

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

SearchApplication

Optional

Microsoft.Office.Server.Search.Cmdlet.SearchServiceApplicationPipeBind

Specifies the search application that contains the managed property collection.

A valid GUID, such as 12345678-90ab-cdef-1234-567890bcdefgh; a valid search application name (for example, SearchApp1); or an instance of a valid SearchServiceApplication object.

WhatIf

Optional

System.Management.Automation.SwitchParameter

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

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

$searchapp = Get-SPEnterpriseSearchServiceApplication "SearchApp1"
$mp = Get-SPEnterpriseSearchMetadataManagedProperty -SearchApplication $searchapp -Identity testmanagedproperty
$prop = Get-SPEnterpriseSearchMetadataCrawledProperty -SearchApplication $searchapp -Name testcrawledproperty
$map = Get-SPEnterpriseSearchMetadataMapping -SearchApplication $searchapp -CrawledProperty $prop -ManagedProperty $mp
$map | Remove-SPEnterpriseSearchMetadataMapping

This example removes the metadata mapping between the crawled property testcrawledproperty and the managed property testmanagedproperty.
