• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing tan) OR (hong tan)) ping lin lu ((jong min) OR (sang minh)) ((wang hui) OR (wang wei)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing tan) OR (hong tan)) ping lin lu ((jong min) or (sang minh)) ((wang hui) or (wang wei)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing tan) OR (hong tan)) ping lin lu ((jong min) or (sang minh)) ((wang hui) or (wang wei)) ;*.
