• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (chan kang)) klaue der felder age ((((ma kong) OR (ma rong))) OR (ma hong)) sar ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (chan kang)) klaue der felder age ((((ma kong) OR (ma rong))) or (ma hong)) sar ;*".
