• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thuat sach)) ty hoang xa hoi. lieu va cac xuc ((va danh) OR (va dan)) lai chau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thuat sach)) ty hoang xa hoi. lieu va cac xuc ((va danh) OR (va dan)) lai chau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thuat sach)) ty hoang xa hoi. lieu va cac xuc ((va danh) OR (va dan)) lai chau triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thuat sach)) ty hoang xa hoi. lieu va cac xuc ((va danh) OR (va dan)) lai chau triet*.
