• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang xianodong) OR (wang xiaobing)) hong cheng han ((fang ri) OR (vang viet)) dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xianodong) OR (wang xiaobing)) hong cheng han ((fang ri) or (vang viet)) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xianodong) OR (wang xiaobing)) hong cheng han ((fang ri) or (vang viet)) dang hai ;*.
