• If you are trying to use Boolean operators, they must be ALL CAPS: (((wang OR lang) yanling) OR (yan guan)) ((than china) OR (wuhan china)) path gang 2 long run ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((wang or lang) yanling) or (yan guan)) ((than china) OR (wuhan china)) path gang 2 long run ;~".
• Adding a wildcard symbol may retrieve word variants: (((wang or lang) yanling) or (yan guan)) ((than china) OR (wuhan china)) path gang 2 long run ;*.
