• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chuc nang)) - hanh tang cua nhung ((cong van) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chuc nang)) - hanh tang cua nhung ((cong van) OR (cong san)) toan cau*.
