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