• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - ((hanh hang) OR (hang hang)) cua bang cong dan ((chan cau) OR (can cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - ((hanh hang) OR (hang hang)) cua bang cong dan ((chan cau) or (can cau))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - ((hanh hang) OR (hang hang)) cua bang cong dan ((chan cau) or (can cau))*.
