• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang kang) OR (wang yang)) han ((hua gain) OR (heat gain)) yang lin zong hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang kang) or (wang yang)) han ((hua gain) OR (heat gain)) yang lin zong hai ;".
