• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - cang thang va dung cong bai ((toan cau) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - cang thang va dung cong bai ((toan cau) OR (toan tap))".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - cang thang va dung cong bai ((toan cau) OR (toan tap))*.
