Search entire drive using select-string in powershell

HI all using the select-string cmdlet in powershell, I am able to find the path do a file if I'm either in the directory all ready or I specify the entire path to the file using the -Path switch.

Is there a way to get select-string to find the file just by putting in the name of the file?, This without having to specify the whole path?

Any thoughts are appreciated.
