$props = @{

        @{Name="indexName"; Title="Choose an index"; Options=$options; Tooltip="Choose Index"} 
    ) 
    Title = "Index Wizard" 
    Description = "Select an index." 
    Width = 300 
    Height = 300 
    ShowHints = $true 
} 

$result = Read-Variable @props 

if ($result -eq "ok") { 
    $index = [Sitecore.ContentSearch.ContentSearchManager]::GetIndex($indexName) 
}

        write-host $_.Name "SKIPPED" 
    }

         write-host $_.Name $_.Paths.FullPath 
       [Sitecore.ContentSearch.Maintenance.IndexCustodian]::Refresh($index, [Sitecore.ContentSearch.SitecoreIndexableItem]$_) 
    }
