SharePoint 2013 Search: Adding a New Analytics Component to a Search Server

This blog is part of my Scaling Out Search Series and describes the processes for adding a new analytics component to a new search server:

Get Search Service Instance and Start on New Index Server$ssi = Get-SPEnterpriseSearchServiceInstance -Identity "<<new index server>>"
Start-SPEnterpriseSearchServiceInstance -Identity $ssi

Wait for Search Service Instance to come online
Get-SPEnterpriseSearchServiceInstance -Identity $ssi

(The full script contains a loop that waits for the service to come online)

Clone Active Search Topology$ssa = Get-SPEnterpriseSearchServiceApplication
$active = Get-SPEnterpriseSearchTopology -SearchApplication $ssa -Active
$clone = New-SPEnterpriseSearchTopology -SearchApplication $ssa -Clone –SearchTopology $active

Add New Analytics Processing Component
New-SPEnterpriseSearchAnalyticsProcessingComponent -SearchTopology $clone -SearchServiceInstance $ssi

Activate the Cloned Search Topology
Set-SPEnterpriseSearchTopology -Identity $clone


Review new topology
Get-SPEnterpriseSearchTopology -Active -SearchApplication $ssa


Monitor Distribution of Index
Get-SPEnterpriseSearchStatus -SearchApplication $ssa

(The full script contains a loop that waits for the index component to be Active)

The new index component will be "Degraded" until the index is fully synced. Use the -text parameter to retrieve more detailed information.

Once all components are Active, reviewing the Search Application Topology in Central Admin shows the following:

NEXT, I created a New Admin Component.
