• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu khach)) ty hang mai hoi. hieu ((va nham) OR (va nha)) thuc va tinh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu khach)) ty hang mai hoi. hieu ((va nham) or (va nha)) thuc va tinh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (vu khach)) ty hang mai hoi. hieu ((va nham) or (va nha)) thuc va tinh vai cua tre*.
