• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc nhiet) OR (hoc thiet)) tach - hanh truong cua nhung ((cong san) OR (cong tac)) tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc nhiet) OR (hoc thiet)) tach - hanh truong cua nhung ((cong san) or (cong tac)) tuan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc nhiet) OR (hoc thiet)) tach - hanh truong cua nhung ((cong san) or (cong tac)) tuan cau*.
