• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu lanh va hoi. lieu va ((cam duc) OR (dao duc)) van ((hanh lam) OR (thanh lap)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu lanh va hoi. lieu va ((cam duc) or (dao duc)) van ((hanh lam) OR (thanh lap)) cua tre".
