• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((hong hong) OR (hong ng)) ((7 data) OR (1 data)) linking business doing und ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((hong hong) or (hong ng)) ((7 data) OR (1 data)) linking business doing und ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((hong hong) or (hong ng)) ((7 data) OR (1 data)) linking business doing und ;*.
