• If you are trying to use Boolean operators, they must be ALL CAPS: vu khac ty tang ((ma hoi) OR (ma hoa)). hieu vu cham duc ((va hanh) OR (va thanh)) lam cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khac ty tang ((ma hoi) OR (ma hoa)). hieu vu cham duc ((va hanh) or (va thanh)) lam cuu tre*".
