Pause the Search Service Application by using Windows PowerShell

Hi there,

Issues again with using the Sharepoint 2013 Management Shell

Following the TechNet notes on http://technet.microsoft.com/en-us/library/jj219654.aspx

I have got to the point where it is asking me to Pause the Search Service Application and to enter in the following command -

$ssa = Get-SPEnterpriseSearchServiceApplication <Search Service Application>
Suspend-SPEnterpriseSearchServiceApplication -Identity $ssa

The search service application is named Search Service Application as screen shot shows below -
