• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (so sach)) ky lang ha hoi. hieu ((qua cac) OR (cua cac)) xuc va danh di cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (so sach)) ky lang ha hoi. hieu ((qua cac) OR (cua cac)) xuc va danh di cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (so sach)) ky lang ha hoi. hieu ((qua cac) OR (cua cac)) xuc va danh di cua viet*".
