ANA is one of the most reliable and most comprehensive sites available to find award seats on flights operated by Star Alliance members.
A couple years ago they changed their policies and took away the ability to search for partner awards if you have no miles in your (free) account making it no longer so free or easy.
There are a couple workarounds but this is the quickest; it puts the button back just like it should be.
