Is there a way to view Star Alliance Partner flights on the new search engine? The Help window suggests a filter to include them is available:
Reward type:
*******************************************
Choose one or more reward types to see the results that are specific to your selection.

ClassicFlight rewards are based on the ClassicFlight rewards chart.

Star Alliance Flight rewards are based on the Star Alliance Flight rewards chart.

ClassicPlus Flight rewards provide access to all seats on Air Canada & Air Canada Jazz flights. These flights reward mileage levels may vary on a ticket by ticket basis

*************************************************
However, all I see are AC options, and, the filter (to refine search) seems to be limited to:

fewest miles - shortest travel time

and - Reward Type

Classic
Classic Plus

with no way of inclusion of other Star Alliance carriers ??

For example, for YWG-GRU there used to be various UA options

thanks
