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