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