• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thieu) OR (hoc hien)) sach - tinh bang luan hang luong dan ((toan tap) or (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) sach - tinh bang luan hang luong dan ((toan tap) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (hoc hien)) sach - tinh bang luan hang luong dan ((toan tap) or (toan ban))*".
