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