Odoo 11.0 make field unique

问题

Can somebody explain how to make a field unique value? Like the invoice number, order number, ... each value must be unique.

I need this for the product internal_reference and contact reference too. I've been checking the parameters for these fields via Odoo Studio app, but I don't see anything how to make them unique.

Thanks
