I've used PicasaWeb's facial recognition tools to tag all the people in my pictures... now is there a way to search for pictures that contain specific groups of people?  Examples:Alice AND BobCarl ONLYDavid NOT EdgarFrank OR George(I know you can do the AND case using the checkboxes on the people tab)
In PicasaWeb, how can I find pictures that contain Person A and Person B?
