• Performing a fuzzy search may retrieve terms with similar spellings: te sach y tang ((van hoi) or (van hoc)). hieu ve cham luc va dinh cau ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y tang ((van hoi) OR (van hoc)). hieu ve cham luc va dinh cau ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y tang ((van hoi) or (van hoc)). hieu ve cham luc va dinh cau ((cua triet) OR (su triet))*".
