• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chiet tach)) - ((hang hang) OR (cang thang)) va thu phuong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chiet tach)) - ((hang hang) OR (cang thang)) va thu phuong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chiet tach)) - ((hang hang) OR (cang thang)) va thu phuong dan toan cao*.
