• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi sach) OR (chinh sach)) - thanh tran xuan ((nhung don) OR (thong cong)) van thang cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi sach) OR (chinh sach)) - thanh tran xuan ((nhung don) or (thong cong)) van thang cau".
• Adding a wildcard symbol may retrieve word variants: doi ((chi sach) OR (chinh sach)) - thanh tran xuan ((nhung don) or (thong cong)) van thang cau*.
