Remove Search Service Application in SharePoint 2010

I have a problematic Search Service Application(SSA) in the SP 2010 farm after patching the SP1, the SSA is always in starting mode or stopping mode when I click stop...it never complete the task successfully... and I can't delete the SSA in Central Admin neither... So I turned to Powershell and the good old stsadm.

Here are the steps

Run cmdlet to get SSA id (the guid)

Get-SPEnterpriseSearchServiceApplication

Then run 

Stsadm -o deleteconfigurationobject -id  <GUID>

Then you should see the SSA gone away successfully.

To re-setup the search for SharePoint 2010, you can follow the script to Russ Maxwell

Tips:
You can also use PowerShell to setup Sharepoint 2010 Search Crawl Schedules. Just follow
