• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - anh tang cua ((nhung van) OR (thong cong)) dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - anh tang cua ((nhung van) or (thong cong)) dan toan cau*.
