• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - ((manh trung) OR (hanh trang)) cua khong cong ban than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - ((manh trung) or (hanh trang)) cua khong cong ban than cap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - ((manh trung) or (hanh trang)) cua khong cong ban than cap*.
