• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (wang yan))) OR (wang handling)) yi hua chen yang min wong yue ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yang) OR (wang yan))) or (wang handling)) yi hua chen yang min wong yue ;".
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) OR (wang yan))) or (wang handling)) yi hua chen yang min wong yue ;*.
