• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ying hua le ((duong van) OR (cong van)) ((chuang hui) OR (chun hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ying hua le ((duong van) or (cong van)) ((chuang hui) OR (chun hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ying hua le ((duong van) or (cong van)) ((chuang hui) OR (chun hui)) ;*.
