Removes a crawled-property-to-managed-property mapping.

Syntax

Remove-FASTSearchMetadataCrawledPropertyMapping -CrawledProperty <CrawledProperty> -ManagedProperty <ManagedProperty> [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

Detailed Description

This cmdlet removes the mapping of a crawled property to a managed property. Both the managed property and the crawled property still exist after the mapping is removed.

The cmdlet parameters are both objects, and must be retrieved separately.

The content must be recrawled/re-fed for the search index to reflect that the mapping was removed.

Parameters

Parameter	Required	Type	Description
CrawledProperty	Required	Microsoft.SharePoint.Search.Extended.Administration.Schema.CrawledProperty	The crawled property which is having a mapping removed. The object can be retrieved by using Get-FASTSearchMetadataCrawledProperty, or by using the `GetCrawledPropertyMappings()` method call on a managed property object.
ManagedProperty	Required	Microsoft.SharePoint.Search.Extended.Administration.Schema.ManagedProperty	The managed property object which is having a mapping removed. The object can be retrieved by using the Get-FASTSearchMetadataManagedPropertycmdlet.
Confirm	Optional	System.Management.Automation.SwitchParameter	Activates user prompting to confirm the operation. If set, prompting is activated. If Confirm is false (`-Confirm:$false`), confirmation prompting is not used. In cases where Confirm is not specified, the cmdlet will prompt if the `$ConfirmPreference` shell variable is equal to or greater than the ConfirmImpact setting of the cmdlet (HIGH).
Force	Optional	System.Management.Automation.SwitchParameter	Overrides any user prompting settings, so that confirmation of the operation is not required.
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

---------------EXAMPLE 1-----------------

$title = Get-FASTSearchMetadataManagedProperty -name title
$crawledproperties = $title.GetCrawledPropertyMappings()
$crawledproperties # To List the output before the removal
Remove-FASTSearchMetadataCrawledPropertyMapping -managedproperty $title -crawledproperty $crawledproperties[4]
$crawledproperties # To list the output after the removal

This example removes the mapping of the crawled property “sitemap.title” to the managed property “title”.

This example calls the GetCrawledPropertyMappings() method call exposed by the managed property, but you could also find the crawled property by using Get-FASTSearchMetadataCrawledProperty. The return value from GetCrawledPropertyMappings() is an array of crawled properties, of which the last is the “sitemap.title” crawled property mapping. The last of the crawled properties (array index 4) has the mapping removed from it by calling Remove-FASTSearchMetadataCrawledPropertyMapping.
