• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (te sach)) ky nang xa hoi. thien van bac tuc xa ((thanh kem) OR (thanh ke)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (te sach)) ky nang xa hoi. thien van bac tuc xa ((thanh kem) OR (thanh ke)) cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (te sach)) ky nang xa hoi. thien van bac tuc xa ((thanh kem) OR (thanh ke)) cua triet*.
