• If you are trying to use Boolean operators, they must be ALL CAPS: wang dan ((data hua) OR (data human)) wang yang jui ((shang kai) OR (((hong 7) OR (hong ma)))) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan ((data hua) OR (data human)) wang yang jui ((shang kai) or (((hong 7) or (hong ma)))) ;*".
