• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) yan congo can ((((cheng ling) OR (cheng ming))) OR (chen ping)) jin song siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wing) yan congo can ((((cheng ling) or (cheng ming))) or (chen ping)) jin song siu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wing) yan congo can ((((cheng ling) or (cheng ming))) or (chen ping)) jin song siu ;*.
