• If you are trying to use Boolean operators, they must be ALL CAPS: ((dann bin) OR (dong sin)) yams yu ((cheng chung) OR (cheng zhang)) eng hong 7 ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dann bin) or (dong sin)) yams yu ((cheng chung) OR (cheng zhang)) eng hong 7 ;*".
