• If you are trying to use Boolean operators, they must be ALL CAPS: (wan OR wing) yanling ((than china) OR (tuan china)) ((gain yang) OR (tan yang)) tin hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or wing) yanling ((than china) OR (tuan china)) ((gain yang) or (tan yang)) tin hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or wing) yanling ((than china) OR (tuan china)) ((gain yang) or (tan yang)) tin hong hai ;*.
