• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang hong) OR (wang yong)) tan chia dan yang ((xi kang) OR (jin chang)) hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang hong) OR (wang yong)) tan chia dan yang ((xi kang) or (jin chang)) hay ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang hong) OR (wang yong)) tan chia dan yang ((xi kang) or (jin chang)) hay ;*.
