;Open Word document
;Maybe you can do everything invisible and comment the next line
$objWord.Visible = 1
$RC = $objWord.Documents.Open($strWordFile)
$objWord.Selection.Find.Text = $strFind
$RC = $objWord.Selection.Find.Execute

; Other stuff
; Complete your script

;Do not forget to close word if working invisible
$RC = $objWord.Application.Quit

The File/Open and the Find are easy to recreate if you just play a while with your macro recorder in Word. Just give it a try.
