• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (hong cheng)) ((((yang jun) OR (pang jun))) OR (yang yang)) l kong heng jong min ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (hong cheng)) ((((yang jun) OR (pang jun))) or (yang yang)) l kong heng jong min ;*".
