• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang yang) OR (wang yang))) OR (cargo handling)) li hui chen huang min hong yeon ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang yang) OR (wang yang))) or (cargo handling)) li hui chen huang min hong yeon ;*".
