• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (nang x)) hoi. ((hieu ve) OR (hieu va)) cam xuc van hanh va su triet.
• Adding a wildcard symbol may retrieve word variants: tu sach y ((nang xa) or (nang x)) hoi. ((hieu ve) or (hieu va)) cam xuc van hanh va su triet*.
