• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh ((truong va) OR (truong dao)) dung ((cong khanh) OR (cong dan)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh ((truong va) OR (truong dao)) dung ((cong khanh) or (cong dan)) toan cao".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh ((truong va) OR (truong dao)) dung ((cong khanh) or (cong dan)) toan cao*.
