• If you are trying to use Boolean operators, they must be ALL CAPS: ((qian yan) OR (((dong jung) OR (yang yang)))) e a yuan chang minh ((cong hui) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((qian yan) or (((dong jung) or (yang yang)))) e a yuan chang minh ((cong hui) OR (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((qian yan) or (((dong jung) or (yang yang)))) e a yuan chang minh ((cong hui) OR (gong hui)) ;*.
