• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tay dang van hoc. lieu va cac nuoc ((va nang) OR (van nang)) tai ((cuc te) or (cuc tieu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tay dang van hoc. lieu va cac nuoc ((va nang) OR (van nang)) tai ((cuc te) OR (cuc tieu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tay dang van hoc. lieu va cac nuoc ((va nang) OR (van nang)) tai ((cuc te) or (cuc tieu))*".
