• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) xanh - canh ((tranh luat) OR (trinh luan)) thanh duong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) xanh - canh ((tranh luat) or (trinh luan)) thanh duong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (toc thieu)) xanh - canh ((tranh luat) or (trinh luan)) thanh duong dan toan cau*.
