New-SPEnterpriseSearchMetadataCategory [-Name] <String> -SearchApplication <SearchServiceApplicationPipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-AutoCreateNewManagedProperties <Nullable>] [-Confirm [<SwitchParameter>]] [-DiscoverNewProperties <Nullable>] [-MapToContents <Nullable>] [-PropSet <Nullable>] [-WhatIf [<SwitchParameter>]]

Parameters

Parameter Required Type Description

Name

Required

System.String

Specifies the identity of the new metadata category.

The type must be a valid name of a metadata category, for example, MetadataCategory1.

SearchApplication

Required

Microsoft.Office.Server.Search.Cmdlet.SearchServiceApplicationPipeBind

Specifies the search service application that contains the enterprise search metadata categories.

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

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.

AutoCreateNewManagedProperties

Optional

System.Nullable

Specifies that when a new crawled property in this category is found, a corresponding managed property is created and mapped to this new crawled property.

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

DiscoverNewProperties

Optional

System.Nullable

Specifies that if there are unknown properties in this category, these new properties are discovered during a crawl.

MapToContents

Optional

System.Nullable

Specifies that all crawled properties of type string are mapped to corresponding managed properties of this category.

PropSet

Optional

System.Nullable

Creates a new metadata category with the specified property set.

Note that the specified property set is the identifier of the category. Therefore, two categories cannot share a property set.

The type must be a valid GUID that specifies the property set, in the form 12345678-90ab-cdef-1234-567890bcdefgh.

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

Input Types

Return Types

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

$searchapp = Get-SPEnterpriseSearchServiceApplication
$guid = [System.Guid]::NewGuid()

New-SPEnterpriseSearchMetadataCategory -SearchApplication $searchapp -Name MyCategory -DiscoverNewProperties $true -PropSet $guid

This example adds a new metadata category named MyCategory to the default search service application. The DiscoverNewProperties parameter is set to true. Therefore, new crawled properties will be added to the MyCategory metadata category and the unique category identifier is set with the PropSet parameter.
