Hello,

1. By default, Woocommerce does not provide such an option. You will need a plugin. I heard this one does: YITH WooCommerce Ajax Search

Please note we have not tested this plugin with our theme. We do not guarantee 100% compatibility.

2. You can see the complete demo import video here:

Best Regards.
