• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) tinh - anh quang luan ban ((cong thanh) OR (cuon danh)) tuan cau~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) tinh - anh quang luan ban ((cong thanh) or (cuon danh)) tuan cau*.
