Move Search Components To Different Server in SharePoint 2013


SharePoint 2013 Search components are very scalable. Now you can move the components from the search to different servers which it is running. In SharePoint farm environment usually the Application Server will host all the Services including the Search Application services. The Search Application consists of several Search components like

  • Admin
  • Crawler
  • Content Processing
  • Analytics processing
  • Query Processing
  • Index

The movement of the components to another server is not possible from the Central Administration. The Search Topology does not provide any option to move. So these can be done using the PS commands.

Below is the PS script for the activity.

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

$Srv2 = Get-SPEnterpriseSearchServiceInstance -Identity “Server Name Here
New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $clone -SearchServiceInstance $Srv2
New-SPEnterpriseSearchAnalyticsProcessingComponent -SearchTopology $clone -SearchServiceInstance $Srv2
New-SPEnterpriseSearchContentProcessingComponent -SearchTopology $clone -SearchServiceInstance $Srv2
New-SPEnterpriseSearchCrawlComponent -SearchTopology $clone -SearchServiceInstance $Srv2

Start-SPEnterpriseSearchServiceInstance -Identity $Srv2
Set-SPEnterpriseSearchTopology -Identity $clone
—————-
Clone again to remove original

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

Get-SPEnterpriseSearchComponent -SearchTopology $clone  — to get the component id for the subsequent commands

Remove-SPEnterpriseSearchComponent -Identity  COMPID -SearchTopology $clone -confirm:$false
Remove-SPEnterpriseSearchComponent -Identity COMPID -SearchTopology $clone -confirm:$false
Remove-SPEnterpriseSearchComponent -Identity COMPID -SearchTopology $clone -confirm:$false
Remove-SPEnterpriseSearchComponent -Identity COMPID -SearchTopology $clone -confirm:$false

Set-SPEnterpriseSearchTopology -Identity $clone

—–

Replace the Server Name Here with the server you want to move

COMPID i the old component id of the search component to be removed. You can get all component running on the server by using the command

Get-SPEnterpriseSearchComponent -SearchTopology $clone
