• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ty nang co hoi. hieu ve cac dua ban hang tai ((cuu tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ty nang co hoi. hieu ve cac dua ban hang tai ((cuu tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ty nang co hoi. hieu ve cac dua ban hang tai ((cuu tre) or (cua te))*".
