• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang ma hoi. lieu va ((tham tuc) OR (tham thuc)) ((ban thanh) or (ban hanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang ma hoi. lieu va ((tham tuc) OR (tham thuc)) ((ban thanh) OR (ban hanh)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ma hoi. lieu va ((tham tuc) OR (tham thuc)) ((ban thanh) or (ban hanh)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach y nang ma hoi. lieu va ((tham tuc) OR (tham thuc)) ((ban thanh) or (ban hanh)) vi cua triet*.
