• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - nhanh trinh cua nhung cong ((manh toan) OR (anh tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - nhanh trinh cua nhung cong ((manh toan) or (anh tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - nhanh trinh cua nhung cong ((manh toan) or (anh tuan)) cau*.
