• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - hanh trinh ((quan dung) OR (quan duong)) cong manh ((toan tai) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - hanh trinh ((quan dung) OR (quan duong)) cong manh ((toan tai) or (toan ban))*".
