• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) ((tan hua) OR (yuan hui)) jie kang kim doing von ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) OR (wang yan)) ((tan hua) or (yuan hui)) jie kang kim doing von ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) OR (wang yan)) ((tan hua) or (yuan hui)) jie kang kim doing von ;*.
