• If you are trying to use Boolean operators, they must be ALL CAPS: moc ((chau tinh) OR (ha tinh)) - hanh trung cua ((nhung don) OR (hang cong)) van toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "moc ((chau tinh) OR (ha tinh)) - hanh trung cua ((nhung don) or (hang cong)) van toan cau".
• Adding a wildcard symbol may retrieve word variants: moc ((chau tinh) OR (ha tinh)) - hanh trung cua ((nhung don) or (hang cong)) van toan cau*.
