• If you are trying to use Boolean operators, they must be ALL CAPS: ((hong kyoung) OR (hwang byoung)) yang ((hao zhang) OR (ceo zhang)) hong wang yong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hong kyoung) OR (hwang byoung)) yang ((hao zhang) or (ceo zhang)) hong wang yong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((hong kyoung) OR (hwang byoung)) yang ((hao zhang) or (ceo zhang)) hong wang yong yu ;*.
