• Performing a fuzzy search may retrieve terms with similar spellings: te sach y dang ((xay hoi) or (tay hoi)). hieu va ((cam cuc) OR (pham cuc)) ban hanh hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y dang ((xay hoi) OR (tay hoi)). hieu va ((cam cuc) OR (pham cuc)) ban hanh hai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y dang ((xay hoi) or (tay hoi)). hieu va ((cam cuc) OR (pham cuc)) ban hanh hai cua triet*".
