• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong bin) OR (dong di))) OR (dong skin)) ya hua gain shang tin hong hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong bin) OR (dong di))) or (dong skin)) ya hua gain shang tin hong hai ;".
• Adding a wildcard symbol may retrieve word variants: ((((dong bin) OR (dong di))) or (dong skin)) ya hua gain shang tin hong hai ;*.
