• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang man) OR (wang dan)) chat a gene long thanh ((one mail) OR (e mail)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang man) or (wang dan)) chat a gene long thanh ((one mail) OR (e mail)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang man) or (wang dan)) chat a gene long thanh ((one mail) OR (e mail)) ;*.
