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