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