• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach dao nang ma hoi. hieu va ((cau luc) OR (cau truc)) van anh dat ((cua te) OR (cua su)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach dao nang ma hoi. hieu va ((cau luc) OR (cau truc)) van anh dat ((cua te) or (cua su))".
