• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach _ lang van hoa. hieu ve cham tuc ((((va anh) OR (van anh))) OR (va hanh)) di cua cu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach _ lang van hoa. hieu ve cham tuc ((((va anh) OR (van anh))) or (va hanh)) di cua cu*".
