I finally got the scripts a week ago to configure search. Our SharePoint went down hard. I rebuilt SharePoint and I am running the exact same scripts as before. The screen bleeds red and I can't get continue.
$ssa = Get-SPEnterpriseSearchServiceApplication
$newSearchServerTopology = New-SPEnterpriseSearchTopology -SearchApplication $ssa
I get in red: New-SPEnterpriseSearchTopolgy : Cannot bind to parameter Search application because it is null...
I have tried everything in the comments here. The script is from Todd's book.
