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