• If you are trying to use Boolean operators, they must be ALL CAPS: ((duong van) OR (((dong jung) OR (dong di)))) a la central banks ((jin song) OR (jie song)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((duong van) or (((dong jung) or (dong di)))) a la central banks ((jin song) OR (jie song)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((duong van) or (((dong jung) or (dong di)))) a la central banks ((jin song) OR (jie song)) shu ;*.
