Using powershell create, modify and delete search scope display group in SharePoint 2010

In this article we will be seeing how to create, modify and delete scope display group using powershell script in SharePoint 2010.

Create scope display group:

In the SharePoint site you can create a new display group for the search scope and associate the scope with the group.

Through UI you can go to Site Actions => Site Settings =>Site Administration => Search Scopes => Display group => Create a new display group.

The same thing can be achieved using powershell script

$siteURL="http://servername:1111/"
$site=get-spsite $siteURL
$displayName="CustomDisplayGroup"
$displayDescription="Custom Display Group"
$owningSiteURL=New-Object System.Uri($site.URL)
$displayInAdminUI=$true
$scope1="CustomSiteScope"
$scope2="CustomScope"
$defaultScope=$scope2

$searchContext=[Microsoft.Office.Server.Search.Administration.SearchContext]::GetContext($site)
$scopes=New-Object Microsoft.Office.Server.Search.Administration.Scopes($searchContext)
$displayGroupColl=$scopes.AllDisplayGroups
$displayGroup=$displayGroupCOll.Create($displayName,$displayDescription,$owningSiteURL,$displayInAdminUI)
$displayGroup.Add($scopes.GetSharedScope($scope1))
$displayGroup.Add($scopes.GetSharedScope($scope2))
$displayGroup.Default=$scopes.GetSharedScope($defaultScope)
$displayGroup.Update()

Modify scope display group:

Here we will be modifying the existing display group using powershell script.

$siteURL="http://servername:1111/"
$site=get-spsite $siteURL
$displayName="CustomDisplayGroup"
$newDisplayName="CustomDisplayGroupNew"
$newDisplayDescription="Custom Display Group New"
$owningSiteURL=New-Object System.Uri($site.URL)
$displayInAdminUI=$true
$removeScope="CustomSiteScope"
$addScope="BNew"

$searchContext=[Microsoft.Office.Server.Search.Administration.SearchContext]::GetContext($site)
$scopes=New-Object Microsoft.Office.Server.Search.Administration.Scopes($searchContext)
$displayGroup=$scopes.GetDisplayGroup($owningSiteURL,$displayName)
$displayGroup.Name=$newDisplayName
$displayGroup.Description=$newDisplayDescription
$displayGroup=$displayGroupCOll.Create($displayName,$displayDescription,$owningSiteURL,$displayInAdminUI)
$displayGroup.Remove($scopes.GetSharedScope($removeScope))
$displayGroup.Add($scopes.GetSharedScope($addScope))
$displayGroup.Update()

Delete scope display group:

$siteURL="http://servername:1111/"
$site=get-spsite $siteURL
$displayName="CustomDisplayGroupNew"

$searchContext=[Microsoft.Office.Server.Search.Administration.SearchContext]::GetContext($site)
$scopes=New-Object Microsoft.Office.Server.Search.Administration.Scopes($searchContext)
$displayGroup=$scopes.GetDisplayGroup($owningSiteURL,$displayName)
$displayGroup.Delete()
