chang min » chang mae, chan ming, chang ann
sang minh » kang minah, anh minh, song min

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yang li lee ((((chang min) OR (zhang ming))) OR (sang minh)) tong hui ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang li lee ((((chang min) OR (zhang ming))) or (sang minh)) tong hui ;".
• Adding a wildcard symbol may retrieve word variants: wang yang yang li lee ((((chang min) OR (zhang ming))) or (sang minh)) tong hui ;*.
