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