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