Manual Add Order Product Search Issue

This cannot be customised unfortunately as its in a private file https://github.com/woothemes/woocommerce/blob/master/includes/class-wc-ajax.php#L1804

Thanks for the reply.

Is there any way of having this selectable in the admin settings then? Or is there a way to override it in the functions.php?

Thank you

You could hijack the ajax post but tbh I don’t know if its worth it. You cannot modify this code directly, and I don’t think we’ll change the core search behaviour since it may be beneficial to some users as is.
