ShellExecute "find" Windows Explorer (Search All or Part of the file name)

I am using the following ShellExecute command to open windows explorer "P:" and also display the Search Companion.

Sub Open_ExplorerWindow()
ShellExecute 0, "find", "p:", 0, 0, 1
End Sub

I am interested in also performing a file name search (in all directory folders and subfolders) for the following criteria ( *_136_PC_*.xls ).

How may I populate the "All or Part of the file name" field with the above criteria (and then perhaps also select the Search Button)?

Regards.
