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