• If you are trying to use Boolean operators, they must be ALL CAPS: ((ping wang) OR (lang lang)) yan je chin chang ((zhang rong) OR (zheng rong)) yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ping wang) or (lang lang)) yan je chin chang ((zhang rong) OR (zheng rong)) yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((ping wang) or (lang lang)) yan je chin chang ((zhang rong) OR (zheng rong)) yu ;*.
