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