• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yan) OR (hong cheng))) OR (huang ying)) yang di yu gang ((jin wong) OR (john wong)) siu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yan) or (hong cheng))) or (huang ying)) yang di yu gang ((jin wong) OR (john wong)) siu ;*".
