• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - ((hanh trang) OR (hanh trinh)) cua hang cong dan ((khan cap) OR (khan ap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu xanh - ((hanh trang) or (hanh trinh)) cua hang cong dan ((khan cap) OR (khan ap))~".
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - ((hanh trang) or (hanh trinh)) cua hang cong dan ((khan cap) OR (khan ap))*.
