• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yong)) yan xi ((yi rong) OR (((li cong) OR (kim song)))) minh congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang yong)) yan xi ((yi rong) or (((li cong) or (kim song)))) minh congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) OR (wang yong)) yan xi ((yi rong) or (((li cong) or (kim song)))) minh congo shu ;*.
