• If you are trying to use Boolean operators, they must be ALL CAPS: ((yuan chang) OR (yang yang)) tan hua ren ((yang jin) OR (yang xi)) ((tong shui) OR (tong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan chang) or (yang yang)) tan hua ren ((yang jin) or (yang xi)) ((tong shui) OR (tong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan chang) or (yang yang)) tan hua ren ((yang jin) or (yang xi)) ((tong shui) OR (tong hui)) ;*.
