Image search help

Here is my code so far

#include <ImageSearch.au3>

HotKeySet("`", "Start")
$y = 0
$x = 0

Func start()
   $Search = _ImageSearch('Search.bmp', 0, $x, $y, 0)
If $search = 1 Then
MouseMove($x, $y, 10)
EndIf
EndFunc

while 1
sleep(100)
WEnd

 I want this to actually keep looking for the image in a loop, I have tried a few ways so i deleted my attempts at the loop and let you guys take a look at it

On a side note, I want this to search my 2nd monitor(left of my main monitor) would i put my numbers negative because as of now it only works on my main monitor.
