• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sanh)) v nang xa hoi. thien van bach ((tuoc va) OR (thuoc va)) hanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sanh)) v nang xa hoi. thien van bach ((tuoc va) OR (thuoc va)) hanh di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sanh)) v nang xa hoi. thien van bach ((tuoc va) OR (thuoc va)) hanh di cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sanh)) v nang xa hoi. thien van bach ((tuoc va) OR (thuoc va)) hanh di cua triet*.
