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