SearchServiceInstance

Required

Microsoft.Office.Server.Search.Cmdlet.SearchServiceInstancePipeBind

Specifies the search service instance that will host the new index component. The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh, a valid name of a search topology server, or an instance of a valid SearchServiceInstance object.

SearchTopology

Required

Microsoft.Office.Server.Search.Cmdlet.SearchTopologyPipeBind

Specifies the search topology where the new index component should be added.

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.

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

IndexPartition

Optional

System.UInt32

Specifies the index partition number to assign to the new search index component.

RootDirectory

Optional

System.String

Specifies the root directory that will hold the index location for the new search index component. This is needed if you want to isolate the index on dedicated discs in order to avoid I/O contention with other parts of the system, other system sharing the same disks, or because you do not want to risk the index filling up the OS disk (generally C: )

Note:
If you specify the root directory to be the root of a volume, e.g. E:, the index will not be cleaned up if you delete the SSA. You will then have to delete the index files manually.

SearchApplication

Optional

Microsoft.Office.Server.Search.Cmdlet.SearchServiceApplicationPipeBind

Specifies the search service application that contains the search topology.

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
