• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - thanh trung ap dung ((cong tan) OR (cong ty)) ran cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - thanh trung ap dung ((cong tan) or (cong ty)) ran cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - thanh trung ap dung ((cong tan) or (cong ty)) ran cau*.
