• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach tranh ((cong khi) OR (khong khi)) đong luc ) OR ( cuon sach ngon co khi đong luc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach tranh ((cong khi) OR (khong khi)) đong luc ) or ( cuon sach ngon co khi đong luc ))".
• Adding a wildcard symbol may retrieve word variants: (( su sach tranh ((cong khi) OR (khong khi)) đong luc ) or ( cuon sach ngon co khi đong luc ))*.
