• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thuat sach)) ky nang xa hoi. hieu va cham thuoc ban hang ((vi su) OR (va su)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thuat sach)) ky nang xa hoi. hieu va cham thuoc ban hang ((vi su) OR (va su)) triet".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (thuat sach)) ky nang xa hoi. hieu va cham thuoc ban hang ((vi su) OR (va su)) triet*.
