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