• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (chiet tach)) - thanh tran xuan hung cong dan ((than cau) OR (toan cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chiet tach)) - thanh tran xuan hung cong dan ((than cau) OR (toan cau))".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (chiet tach)) - thanh tran xuan hung cong dan ((than cau) OR (toan cau))*.
