Applies to: SharePoint Server 2010

Topic Last Modified: 2010-02-11

Creates a crawl component for a shared search application.

New-SPEnterpriseSearchCrawlComponent -CrawlDatabase <CrawlStorePipeBind> -CrawlTopology <CrawlTopologyPipeBind> -SearchServiceInstance <SearchServiceInstancePipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-Confirm [<SwitchParameter>]] [-IndexLocation <String>] [-SearchApplication <SearchServiceApplicationPipeBind>] [-WhatIf [<SwitchParameter>]]

The New-SPEnterpriseSearchCrawlComponent cmdlet is run when the search functionality is initially configured, or when a new crawl component is added to a crawl topology for a shared search application. A crawl topology can contain multiple crawl components.

 

Parameter Required Type Description

CrawlStore

Required

Microsoft.Office.Server.Search.Cmdlet.CrawlStorePipeBind

Creates the new crawl component in the specified crawl store.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of a CrawlStore object (for example, CrawlStore1); or an instance of a valid CrawlStore object.

CrawlTopology

Required

Microsoft.Office.Server.Search.Cmdlet.CrawlTopologyPipeBind

Specifies the crawl topology that contains the crawl component collection.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh, or an instance of a valid CrawlTopology object.

SearchServiceInstance

Required

Microsoft.Office.Server.Search.Cmdlet.SearchServiceInstancePipeBind

Specifies the search service instance to host the new crawl component.

The type must be a valid GUID, in the form 12345678-90ab-cdef-1234-567890bcdefgh; a valid name of a query server (for example, MyQueryServer); or an instance of a valid SearchServiceInstance 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

IndexLocation

Optional

System.String

Specifies the path for the index directory where the full-text index files are created.

The type must be a valid path in either of the following forms:

- C:\ folder_name

- \\server_name\folder_name

SearchApplication

Optional

Microsoft.Office.Server.Search.Cmdlet.SearchServiceApplicationPipeBind

Specifies the search application that contains the crawl topology.

The type must be a valid GUID, in the form 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"
$topo = Get-SPEnterpriseSearchCrawlTopology -SearchApplication $searchapp -Identity 00000000-0000-0000-0000-000000000000
New-SPEnterpriseSearchCrawlComponent -SearchApplication $searchapp -CrawlTopology $topo -CrawlDatabase "Sample_Search_Service_Application_CrawlStoreDB" -SearchServiceInstance servername -IndexLocation d:\crawlshare
$topo | Set-SPEnterpriseSearchCrawlTopology -Active

This example retrieves the inactive crawl topology, adds a component, and then activates the topology.
