• If you are trying to use Boolean operators, they must be ALL CAPS: wing ian pong how ((((best chang) OR (best thing))) OR (past changes)) kia hong (seung OR yeung) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ian pong how ((((best chang) OR (best thing))) or (past changes)) kia hong (seung or yeung) ;*".
