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