• Performing a fuzzy search may retrieve terms with similar spellings: su sach v nang ma hoi. hieu ve ((lam truong) or (nam truc)) ((van hanh) OR (van anh)) dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach v nang ma hoi. hieu ve ((lam truong) OR (nam truc)) ((van hanh) OR (van anh)) dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang ma hoi. hieu ve ((lam truong) or (nam truc)) ((van hanh) OR (van anh)) dai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach v nang ma hoi. hieu ve ((lam truong) or (nam truc)) ((van hanh) OR (van anh)) dai cua triet*.
