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