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:
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.

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.

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

WhatIf
