• If you are trying to use Boolean operators, they must be ALL CAPS: wing tan ((han hua) OR (tuan china)) ((tan yang) OR (tan yong)) ((han chang) OR (ying chang)) ha ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing tan ((han hua) or (tuan china)) ((tan yang) OR (tan yong)) ((han chang) or (ying chang)) ha ;~".
• Adding a wildcard symbol may retrieve word variants: wing tan ((han hua) or (tuan china)) ((tan yang) OR (tan yong)) ((han chang) or (ying chang)) ha ;*.
