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