• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang wang lin lu ((sang minh) OR (((song ming) OR (((gong min) OR (jong min)))))) long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang wang lin lu ((sang minh) or (((song ming) or (((gong min) OR (jong min)))))) long shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang wang lin lu ((sang minh) or (((song ming) or (((gong min) OR (jong min)))))) long shu ;*.
