• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ly) OR (sach y)) hang ma hoi. hieu ve ((cam duc) OR (cao duc)) van tuan dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ly) OR (sach y)) hang ma hoi. hieu ve ((cam duc) or (cao duc)) van tuan dai cua te".
