• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (huang weng)) yang yang dia kongo heng ((kong siu) OR (kong eiu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (huang weng)) yang yang dia kongo heng ((kong siu) OR (kong eiu)) ;*".
