• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh trang cua dung cong dan ((gian lang) OR (((giang van) OR (gian dan))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh trang cua dung cong dan ((gian lang) or (((giang van) OR (gian dan))))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh trang cua dung cong dan ((gian lang) or (((giang van) OR (gian dan))))*.
