• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong bin) OR (dong di))) OR (waste handling)) ya six west shang jin hong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong bin) OR (dong di))) or (waste handling)) ya six west shang jin hong shu ;*".
