Looking for Search In Order Comments Add-On

[TheClarkster]

I'm looking for an add-on that will allow me to search in the order comments for key words.

 

For example, I'd like to be able to put an order on backorder, enter into the comments what is backordered.

 

Then when product is in stock, be able to search the backorders for all orders with that product.

 

Is there an Add-on that will do this?

 

Thanks!
