Create SharePoint 2010 Search Scope and Rules using Powershell

For instance, I have 3 site collections and all site collections under same database as shown below.

http://spdev5:8004 (root site colection 1)

http://spdev5:8004/sites/site2   (site collection 2)

http://spdev5:8004/sites/site3  (site collection 3)

By default when I search in the root site collection it displays results from all site collections. For ex if I search something in the root site collection it is showing data of site col2 and site col 3 as well. However if search anything in site col2 or site col3 results are limited to that site collection only. That’s fine.

Below script will create a scope in the central admin and you can see this one in the site collection as well.

In the scope I am including my root level site and excluding site collection2.

$siteURL="rootsitecolurl"

$searchServiceName="Search Service Application"

$scopeName="MyScope"

$docLibraryURL = “sitecoll2url”

 $ssa = Get-SPEnterpriseSearchServiceApplication –Identity $searchServiceName | New-SPEnterpriseSearchQueryScope -Name $scopeName -Description "Include root site collection and Exclude rest of the site collections"  -DisplayInAdminUI $true

$scope = Get-SPEnterpriseSearchQueryScope -SearchApplication $searchServiceName -Identity $scopeName

Write-Host $scope.NAME

$rule1 = New-SPEnterpriseSearchQueryScopeRule -RuleType "Url" -Url $siteURL -MatchingString $siteURL -FilterBehavior "Include" -UrlScopeRuleType "Folder" -scope $scope

$rule2 = New-SPEnterpriseSearchQueryScopeRule -RuleType "Url" -Url $docLibraryURL -MatchingString $docLibraryURL -FilterBehavior "Exclude" -UrlScopeRuleType "Folder" -scope $scope

Write-Host "Scope Created"

#This scope name (MyScope) you have to update in the root site collection search results page #‘OSSSearchResults.aspx’. just look for ‘Scope’ and update as ‘Scope= MyScope’
