• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang mai hoi. hieu ve ((cam dua) OR (cay dua)) ban thanh hai ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang mai hoi. hieu ve ((cam dua) or (cay dua)) ban thanh hai ((cuu tre) OR (cau treo))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang mai hoi. hieu ve ((cam dua) or (cay dua)) ban thanh hai ((cuu tre) OR (cau treo))*.
