• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu sach)) ky ((tang ma) OR (mang may)) hoi. hieu ve cam xuc va thanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky ((tang ma) OR (mang may)) hoi. hieu ve cam xuc va thanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ky ((tang ma) OR (mang may)) hoi. hieu ve cam xuc va thanh vi cua triet*".
