• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang liang) OR (wang yang)) ((wuhan china) OR (yunnan china)) hui ping a long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (wang yang)) ((wuhan china) OR (yunnan china)) hui ping a long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (wang yang)) ((wuhan china) OR (yunnan china)) hui ping a long du ;*.
