• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (chieu xanh)) - anh hang cua bang cong danh ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (chieu xanh)) - anh hang cua bang cong danh ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) or (chieu xanh)) - anh hang cua bang cong danh ((toan cau) OR (toan ban))*.
