When i search for a product or customer name that contains more than one word i have to use _ instead of spaces to get it to work correctly
i.e. Search Term: Fitted_hat_3
This wasn't a problem in previous versions.
also, you can see this problem on your demo site http://demo.storeapps.org/wp-admin/admin.php?page=smart-manager-demo
when you search for "Macbook pro" vs "Macbook_pro"
