• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (((hong hong) OR (hong jong)))) yaa ((yu cheng) OR (yu chen)) yang yu gan yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (((hong hong) or (hong jong)))) yaa ((yu cheng) OR (yu chen)) yang yu gan yue ;*".
