• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach nhanh chong thai đong luc ) OR ( su sach tren ((hoang khi) OR (hoang chi)) đong luc ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach nhanh chong thai đong luc ) or ( su sach tren ((hoang khi) OR (hoang chi)) đong luc ))~".
• Adding a wildcard symbol may retrieve word variants: (( su sach nhanh chong thai đong luc ) or ( su sach tren ((hoang khi) OR (hoang chi)) đong luc ))*.
