• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky nang x hoi. hieu ve cham xuc van nhan ((tai va) OR (tri va)) thiet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ky nang x hoi. hieu ve cham xuc van nhan ((tai va) or (tri va)) thiet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) ky nang x hoi. hieu ve cham xuc van nhan ((tai va) or (tri va)) thiet*.
