• If you are trying to use Boolean operators, they must be ALL CAPS: ((nina sun) OR (dong di)) ((yang guang) OR (yan yuan)) ((sang min) OR (sang minh)) a wong siu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nina sun) or (dong di)) ((yang guang) or (yan yuan)) ((sang min) OR (sang minh)) a wong siu ;*".
