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

This blog is part of my Scaling Out Search Series and describes the processes for adding a new index 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

Create New Index Component for Index Partition 0
New-SPEnterpriseSearchIndexComponent –SearchTopology $clone -SearchServiceInstance $ssi -IndexPartition 0 -RootDirectory "<<server index location>>"

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

 

 

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

 

 

 

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

 

NEXT, I created a New Crawl Component.

SharePoint 2013 Search: Add an Index 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 index component. The query component steps are 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


Create the New Index Component for Index Partition 0
New-SPEnterpriseSearchIndexComponent –SearchTopology $clone -SearchServiceInstance $ssi -IndexPartition 0             -RootDirectory "E:\SPIndex"

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. The new Index Component will need to sync-up.

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

Get-SPEnterpriseSearchStatus -SearchApplication $ssa -text


I now have the Index Partition across two web front ends:
