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