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