Sharepoint 2010 Foundation Search - not working now

From a PowerShell window on the SharePoint server run a Get-SPEnterpriseSearchServiceApplication CmdLet, hopefully it returns the search service. If a search service does not exist you need to create one using New-SPEnterpriseSearchServiceApplicationProxy -SearchApplication $searchServiceApp - (KB).

If the search service exists, check the available disk space on the query server (corresponding TechNet article).

You can also verify that the index service is running via Computer Management\Services, it is named Indexing Service.

1) I open Powershell and entered the line:        Get-SPEnterpriseSearchServiceApplication
I get error that it is not recognized.

2) Went to services and INDEXING SERVICE is not on list. Nothing starts with INDEX on the list

So as I stated, if it isn't there you need to create it.

New-SPEnterpriseSearchServiceApplicationProxy -SearchApplication $searchServiceApp

Select allOpen in new window

@author... do you mean, the cmdlet is not recognized from powershell ??if so please execute this line.
add-pssnapin "microsoft.sharepoint.powershell" and then run Get-SPEnterpriseSearchServiceApplication

Powershell already installed.

I have attempted to run:

Get-SPEnterpriseSearchServiceApplication

from both SharePoint Management Shell AND Windows Powershell and I still get same error.
The term 'Get-SPEnterpriseSearchServiceApplication' is not a recognized name of a cdmlet, function, or operable program.

NOTE:  The search used to work great. It worked for months and months until the day I changed our Domain Administrator password.

I found the answer searching Google.
