• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu cac) OR (tu cac)) ky lang ((van hoi) OR (van hoc)). lieu va cac luc va thanh co cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu cac) OR (tu cac)) ky lang ((van hoi) or (van hoc)). lieu va cac luc va thanh co cua tre*".
