• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu tinh)) - hanh ((trinh cua) OR (trinh quan)) dang huong van toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu tinh)) - hanh ((trinh cua) OR (trinh quan)) dang huong van toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu tinh)) - hanh ((trinh cua) OR (trinh quan)) dang huong van toan cau*.
