How do you connect in powershell to the advanced ediscovery to delete emails

Question

I was successful in creating a case in eDiscovery and performing a search, then using powershell connect , login and delete the emails.

But when I perform a serach in the Advanced eDiscovery, and then use powershell to connect, it returns an error that the searchname doesn't exist. It seems that by default when I use Powershell to login it defaults to connecting to the stand eDiscovery. I noticed that Cases created in eDiscovery can't be seen in Advanced eDiscovery and the other way around.. But any search created in case in eDiscovery can't be used as a name in a search for a case in the Advanced eDiscovery, which leads me to believe that my connection method I am using needs to point to a different URL.
