SharePoint 2013 Search: Add a Query Component to a New Web Front End

I previously moved the query component to my single web front end server (WFE) and then moved the index partition . Now I have a second WFE provisioned and I wanted to create a query and an index component on that server as well. This post outlines the steps for the query component. The index component was next and those steps are outlined here.


Get Search Service Instance and Start on New WFE Server
$ssi = Get-SPEnterpriseSearchServiceInstance -Identity "<<NEW WFE SERVER NAME>>"
Start-SPEnterpriseSearchServiceInstance -Identity $ssi
Start-SPEnterpriseSearchQueryAndSiteSettingsServiceInstance -Identity "<<NEW WFE SERVER NAME>>"


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

In the full script I have a loop that waits for the service to become online.
 

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

Add the New Query Processing Component
New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $clone -SearchServiceInstance $ssi

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

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

Monitor/Verify the Search Status
Get-SPEnterpriseSearchStatus -SearchApplication $ssa

In the full script I have a loop that waits for the index component to become active. If you have two index components, one usually needs to be re-synced.

You may use the -text parameter to get additional information about the search component statuses:

Get-SPEnterpriseSearchStatus -SearchApplication $ssa -text


I now have a Query Processing component on two web front ends:

Next I wanted to expand the index partition across the two WFEs and so I added a new Index Component to WFE2.
