• If you are trying to use Boolean operators, they must be ALL CAPS: lang fang ((yuan lin) OR (yuan zi)) ((chih hang) OR (chin chang)) ong chong lu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang fang ((yuan lin) or (yuan zi)) ((chih hang) OR (chin chang)) ong chong lu ;~".
• Adding a wildcard symbol may retrieve word variants: lang fang ((yuan lin) or (yuan zi)) ((chih hang) OR (chin chang)) ong chong lu ;*.
