• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y ngang cho hoc. hieu ve ((((cac luc) OR (coc luc))) OR (cau luc)) van anh vi cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y ngang cho hoc. hieu ve ((((cac luc) OR (coc luc))) or (cau luc)) van anh vi cua cau*".
