• Performing a fuzzy search may retrieve terms with similar spellings: thu sach o lang xa hoi. thien van ((nam xua) or (((nam mua) OR (nam qua)))) va danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach o lang xa hoi. thien van ((nam xua) OR (((nam mua) OR (nam qua)))) va danh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach o lang xa hoi. thien van ((nam xua) or (((nam mua) OR (nam qua)))) va danh vi cua triet*".
