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