• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((minh tuan) OR (hanh chinh)) ((cua trong) OR (cua truong)) cong dan than cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((minh tuan) or (hanh chinh)) ((cua trong) OR (cua truong)) cong dan than cao".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((minh tuan) or (hanh chinh)) ((cua trong) OR (cua truong)) cong dan than cao*.
