• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang ying) OR (zhang ying)) chang lin ((chun young) OR (chun yuna)) jean ngosong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang ying) or (zhang ying)) chang lin ((chun young) OR (chun yuna)) jean ngosong sam ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang ying) or (zhang ying)) chang lin ((chun young) OR (chun yuna)) jean ngosong sam ;*.
