• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((((yan han) OR (yan clan))) OR (yan zhang)) run ((daun yang) OR (tan yang)) gang gong min ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((((yan han) or (yan clan))) or (yan zhang)) run ((daun yang) OR (tan yang)) gang gong min ;*".
