• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu van chat tuc ((va hanh) OR (va danh)) vi ((cua tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu van chat tuc ((va hanh) OR (va danh)) vi ((cua tre) or (cau treo))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu van chat tuc ((va hanh) OR (va danh)) vi ((cua tre) or (cau treo))*.
