• Performing a fuzzy search may retrieve terms with similar spellings: su sach _ sang ((tao boi) or (tay hoi)). lieu va ((tham soc) OR (cham soc)) va danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach _ sang ((tao boi) OR (tay hoi)). lieu va ((tham soc) OR (cham soc)) va danh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach _ sang ((tao boi) or (tay hoi)). lieu va ((tham soc) OR (cham soc)) va danh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach _ sang ((tao boi) or (tay hoi)). lieu va ((tham soc) OR (cham soc)) va danh vi cua triet*.
