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