• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach thue me gioi cau duong kinh ) OR ( tu cach nang ve gioi cong dong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( thu sach thue me gioi cau duong kinh ) or ( tu cach nang ve gioi cong dong minh ))*.
