Configuring SharePoint 2013 Search Topology

Configuring SharePoint 2013 Search Topology

  • Comments 10

Introduction

When creating the Search Service application , a default topology will be built automatically where all Search components are assigned to the server which is running the Central Administration, in multi servers farm scenario you need to change this topology , the only available way currently is through PowerShell which will provide more flexibility in configuring the topology, (you can NOT modify the topology through UI like you used to do with SharePoint 2010)

 

 

Sample Topology

I will guide you in this post on how to configure 5 servers as the following:

  • 3 front servers running the Query Processing component to handle search query requests from users, the query processing components will be located in the WFE servers.
  • 2 backend servers servers running the rest of Search components , The rest of search components will be located in the Application servers.
  • We will configure the below topology to have all Search components high available (no single point of failure for any components) , even the index partition will be replicated to the other server (replica)

you can refer to the below diagram to have better understanding for the topology we are about to configure:

Before you start

  • make sure that the current user who is going to execute the power shell is added as admin to Search service application

  • Make sure to run the below Powershell commands on the server that is hosting the Central Administration
  • from Central administration – Search Administration page , make sure the index files are empty , Searchable items appears as 0

now let us start by opening the powerShell on the server running the Central administration, make sure to execute all the below commands in the same PowerShell screen, but I have divided them in  below to make them more readable:

where SPAPP-SRV1, SPAPP-SRV2, SPWF-SRV1, SPWF-SRV2, SPWF-SRV3  are the server names

Prepare the topology variables

$hostApp1 = Get-SPEnterpriseSearchServiceInstance -Identity "SPAPP-SRV1"  

$hostApp2 = Get-SPEnterpriseSearchServiceInstance -Identity "SPAPP-SRV2"

$hostWF1 = Get-SPEnterpriseSearchServiceInstance -Identity "SPWF-SRV1"

$hostWF2 = Get-SPEnterpriseSearchServiceInstance -Identity "SPWF-SRV2"

$hostWF3 = Get-SPEnterpriseSearchServiceInstance -Identity "SPWF-SRV3"

Start-SPEnterpriseSearchServiceInstance -Identity $hostApp1

Start-SPEnterpriseSearchServiceInstance -Identity $hostApp2

Start-SPEnterpriseSearchServiceInstance -Identity $hostWF1

Start-SPEnterpriseSearchServiceInstance -Identity $hostWF2

Start-SPEnterpriseSearchServiceInstance -Identity $hostWF3

 

Get services status

Get Search Service Instance status (started or stopped) after running the above commands

Get-SPEnterpriseSearchServiceInstance -Identity $hostApp1
Get-SPEnterpriseSearchServiceInstance -Identity $hostApp2
Get-SPEnterpriseSearchServiceInstance -Identity $hostWF1
Get-SPEnterpriseSearchServiceInstance -Identity $hostWF2
Get-SPEnterpriseSearchServiceInstance -Identity $hostWF3

 

Setting up the topology

$ssa = Get-SPEnterpriseSearchServiceApplication

$newTopology = New-SPEnterpriseSearchTopology -SearchApplication $ssa

#SPAPP-SRV1

New-SPEnterpriseSearchAdminComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp1

 

New-SPEnterpriseSearchCrawlComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp1

 

New-SPEnterpriseSearchContentProcessingComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp1

 

New-SPEnterpriseSearchAnalyticsProcessingComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp1

 

New-SPEnterpriseSearchIndexComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp1 -IndexPartition 0

 

#SPAPP-SRV2

New-SPEnterpriseSearchAdminComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp2

 

New-SPEnterpriseSearchCrawlComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp2

 

New-SPEnterpriseSearchContentProcessingComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp2

 

New-SPEnterpriseSearchAnalyticsProcessingComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp2

 

New-SPEnterpriseSearchIndexComponent -SearchTopology $newTopology

-SearchServiceInstance $hostApp2 -IndexPartition 0

 

#SPWF-SRV1 , SPWF-SRV2 , SPWF-SRV3

New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $newTopology

-SearchServiceInstance $hostWF1

 

New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $newTopology

-SearchServiceInstance $hostWF2

 

New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $newTopology

-SearchServiceInstance $hostWF3

#Activate the Topology

Set-SPEnterpriseSearchTopology -Identity $newTopology

# Verify the Topology 

Get-SPEnterpriseSearchTopology -SearchApplication $ssa

  • Simply brilliant. Thanks for sharing.. You guys are quickly becoming my go to people in SharePoint farm administration..

    Quick Question... I like to run SharePoint 2013 all search components on dedicated application servers including query components.. with new SP2013 guidance around streamlined topology, it is recommended to run both query and index on same server and avoid running on WFEs due to distributed catche. What do you think about that? Any opinions?

  • Hi Nik ,

    glad you liked the post, well runnning the search components on a dedicated search servers is absolutely much better ... im my above post im assuming you dont have the luxury of having dedicated servers for search query processing, your assumption is correct to have query processing and Index on a seperate server together (if you can afford having more servers in your farm).  :)  

  • Thanks Issa.. that's exactly we are going for.. Thanks for reply..

  • All of the commands under the 'setting up the topology' section are truncated, rendering this post unusable.

  • you should see the full commands now... check it

  • I would also suggest to add some pre-requisites e.g. Search Service Application is already provisioned (which you already suggested in your pre-reqs but may not be obvious to many). Additionally, what search services (e.g. host controller, search settings, and server search services) are started on which server before running this command.. it would make it much clear for readers to see what are starting point...

  • Very useful information. Thank you

    If anyone wants to look at SharePoint search 2013 architecture and configuration

  • can't get it to work...got  one WFE and one APP....

  • Useful info to understand Search topology........ :)

  • thanks you very much, it is very clear and clean
