• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((thiet tach) OR (chiet tach)) - hanh tang cua nhung ((huong van) OR (duong van)) thanh cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((thiet tach) OR (chiet tach)) - hanh tang cua nhung ((huong van) or (duong van)) thanh cau".
• Adding a wildcard symbol may retrieve word variants: ho ((thiet tach) OR (chiet tach)) - hanh tang cua nhung ((huong van) or (duong van)) thanh cau*.
