• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang x hoi. hieu va tham duc ((phan banh) OR (((tang binh) OR (thanh binh)))) d cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang x hoi. hieu va tham duc ((phan banh) or (((tang binh) OR (thanh binh)))) d cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang x hoi. hieu va tham duc ((phan banh) or (((tang binh) OR (thanh binh)))) d cua tre*.
