Woocommerce orders and users names

Hi, this search seems to be a good potential to search users but it doesnt allow you to search by their registered first name or surname but only their given username? Bit limited isnt it? Surely must be an easy way to just search names too and not just their wordpress assigned usernames?

Next issue is it doesnt seem to pick up any woocommerce orders to search from?

Any help would be much appreciated.

thanks
