• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (((yang yang) OR (dong ping)))) ((ya your) OR (day your)) best data mun kyoung yun ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (((yang yang) or (dong ping)))) ((ya your) OR (day your)) best data mun kyoung yun ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (((yang yang) or (dong ping)))) ((ya your) OR (day your)) best data mun kyoung yun ;*.
