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