• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (hoc anh)) ky lang xa hoi. hieu ve cam thuc va ((hang dieu) OR (hoang dieu)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (hoc anh)) ky lang xa hoi. hieu ve cam thuc va ((hang dieu) OR (hoang dieu)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (hoc anh)) ky lang xa hoi. hieu ve cam thuc va ((hang dieu) OR (hoang dieu)) cuu tre*".
