• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (hieu nganh)) - hanh trang cua hang ((luong van) OR (luong vat)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) OR (hieu nganh)) - hanh trang cua hang ((luong van) or (luong vat)) toan cau".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu manh) OR (hieu nganh)) - hanh trang cua hang ((luong van) or (luong vat)) toan cau*.
