• If you are trying to use Boolean operators, they must be ALL CAPS: ((long han) OR (((ong kong) OR (hong kong)))) ya hua test a yi tong shui ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long han) or (((ong kong) OR (hong kong)))) ya hua test a yi tong shui ;~".
• Adding a wildcard symbol may retrieve word variants: ((long han) or (((ong kong) OR (hong kong)))) ya hua test a yi tong shui ;*.
