• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hieu manh - hanh trang cua ((cong lang) OR (cong quang)) ((dan toan) OR (van tuan)) ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - hanh trang cua ((cong lang) OR (cong quang)) ((dan toan) or (van tuan)) ban*".
