• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sinh ky nang cao hoa. hieu ve ((cau phuc) OR (cau truc)) va hanh di ((cua te) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sinh ky nang cao hoa. hieu ve ((cau phuc) OR (cau truc)) va hanh di ((cua te) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: hoc sinh ky nang cao hoa. hieu ve ((cau phuc) OR (cau truc)) va hanh di ((cua te) or (cuu tre))*.
