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