• If you are trying to use Boolean operators, they must be ALL CAPS: gang yang yang hua ((yin fang) OR (((chin fang) OR (chin chang)))) jun ((chang ha) OR (hong ng)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "gang yang yang hua ((yin fang) or (((chin fang) OR (chin chang)))) jun ((chang ha) or (hong ng)) ;~".
• Adding a wildcard symbol may retrieve word variants: gang yang yang hua ((yin fang) or (((chin fang) OR (chin chang)))) jun ((chang ha) or (hong ng)) ;*.
