• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu xanh) OR (dieu hanh)) - hanh tranh van nhung cong san ((than cap) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) or (dieu hanh)) - hanh tranh van nhung cong san ((than cap) OR (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) or (dieu hanh)) - hanh tranh van nhung cong san ((than cap) OR (khan cap))*.
