• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chuc danh) OR (chu manh)) - hanh tang cua nhung cong san ((tan cau) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc danh) or (chu manh)) - hanh tang cua nhung cong san ((tan cau) OR (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chu manh)) - hanh tang cua nhung cong san ((tan cau) OR (toan cau))*.
