• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((dang xa) OR (dang xay)) hoi. hieu ((ve cam) OR (va cac)) duc van thanh hai su triet.
• Adding a wildcard symbol may retrieve word variants: su sac ky ((dang xa) or (dang xay)) hoi. hieu ((ve cam) or (va cac)) duc van thanh hai su triet*.
