• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang yang ((xi ai) OR (ai a)) ((jong min) OR (gong min)) tong shui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang yang ((xi ai) or (ai a)) ((jong min) OR (gong min)) tong shui ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang yang ((xi ai) or (ai a)) ((jong min) OR (gong min)) tong shui ;*.
