Article Summary: Changing the search topology in SharePoint 2010/2013

Changing a search topology in SharePoint 2010/2013 is done through PowerShell and should be done is a multi server farm.

If you have an index which is populated on a farm and you want or need to keep it, there are three steps that need to happen:

• Clone the active search topology

• Make changes to the cloned topology

• Make the clone the active search topology for the farm

Assign the hostname of each server to a variable using the Get-
SPEnterpriseSearchServiceInstance cmdlet
$hostA = Get-SPEnterpriseSearchServiceInstance -Identity "Name of the instance"

If you are adding new hosts to the search topology, start the Search instance on each
of these hosts using the Start-SPEnterpriseSearchServiceInstance cmdlet
Start-SPEnterpriseSearchServiceInstance -Identity $hostA

Verify the status of search on each host using the Get-SPEnterpriseSearchServiceInstance cmdlet.
Get-SPEnterpriseSearchServiceInstance -Identity $hostA

You must wait until the Status line reads "online" (not "provisioning") for each host
before proceeding

Cloning the active topology is done using the New-SPEnterpriseSearchTopology
$ssa = Get-SPEnterpriseSearchServiceApplication
$active = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Active
$clone = New-SPEnterpriseSearchTopology -SearchApplication $ssa -Clone -SearchTopology $active
You will assign the desired component to the appropriate host(s). Note that these PowerShell
commands are NOT identical to those in the previous section

Admin Component

New-SPEnterpriseSearchAdminComponent -SearchTopology $clone -
SearchServiceInstance $hostA

Crawl Component

New-SPEnterpriseSearchCrawlComponent -SearchTopology $clone -
SearchServiceInstance $hostA

Content Processing Component

New-SPEnterpriseSearchContentProcessingComponent -SearchTopology $clone -
SearchServiceInstance $hostA

Analytics Processing

New-SPEnterpriseSearchAnalyticsProcessingComponent -SearchTopology $clone -
SearchServiceInstance $hostA

Index Component

New-SPEnterpriseSearchIndexComponent -SearchTopology $clone -SearchServiceInstance $hostA -IndexPartition 0

Query Processing Component

New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $clone -SearchServiceInstance $hostA

Removing a component requires that you know its Component ID. To get this information, run the Get-SPEnterpriseSearchComponent -SearchTopology $clone PowerShell command

Select the Component ID you wish to delete and use the Remove-SPEnterpriseSearchComponent cmdlet to remove it altogether

Remove-SPEnterpriseComponent -Identity (GUID of the component) -SearchTopology $clone

To activate the new search topology use the Set-SPEnterpriseSearchTopology cmdlet

Set-SPEnterpriseSearchTopology -Identity $clone
