Create a new Search Service Application in SharePoint 2013 using PowerShell


The search architecture in SharePoint 2013 has changed quite a bit when compared to SharePoint 2010. In fact the Search Service in SharePoint 2013 is completely overhauled. It is a combination of FAST Search and SharePoint Search components.


As you can see the query and crawl topologies are merged into a single topology, simply called "Search topology". Provisioning of the search service application creates 4 databases:

  • SP2013_Enterprise_Search - This is a search administration database. It contains configuration and topology information
  • SP2013_Enterprise_Search_AnalyticsReportingStore - This database stores the result of usage analysis
  • SP2013_Enterprise_Search_CrawlStore - The crawl database contains detailed tracking and historical information about crawled items
  • SP2013_Enterprise_Search_LinksStore - Stores the information extracted by the content processing component and also stores click-through information

To configure failover server(s) for Search DBs, use the following PowerShell:

Thanks to Marcel Jeanneau for sharing this!

#Admin Database
$ssa = Get-SPEnterpriseSearchServiceApplication “Search Service Application”
Set-SPEnterpriseSearchServiceApplication –Identity $ssa –FailoverDatabaseServer <failoverServerAlias\instance>

#Crawl Database
$CrawlDatabase0 = ([array]($ssa | Get-SPEnterpriseSearchCrawlDatabase))[0]
Set-SPEnterpriseSearchCrawlDatabase -Identity $CrawlDatabase0 -SearchApplication $ssa -FailoverDatabaseServer <failoverServerAlias\instance>

#Links Database
$LinksDatabase0 = ([array]($ssa | Get-SPEnterpriseSearchLinksDatabase))[0]
Set-SPEnterpriseSearchLinksDatabase -Identity $LinksDatabase0 -SearchApplication $ssa -FailoverDatabaseServer <failoverServerAlias\instance>

#Analytics database
$AnalyticsDB = Get-SPDatabase –Identity <id of database>
$AnalyticsDB.AddFailOverInstance(“failover alias\instance”)
