• If you are trying to use Boolean operators, they must be ALL CAPS: dong (sin OR sink) ya hua rene yan ((((tin hong) OR (tan hong))) OR (thi hong)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong (sin or sink) ya hua rene yan ((((tin hong) OR (tan hong))) or (thi hong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: dong (sin or sink) ya hua rene yan ((((tin hong) OR (tan hong))) or (thi hong)) shu ;*.
