• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chiet tach) OR (chieu sach)) - canh manh cua ((nhung cong) OR (dang cong)) tan hai cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) OR (chieu sach)) - canh manh cua ((nhung cong) or (dang cong)) tan hai cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chiet tach) OR (chieu sach)) - canh manh cua ((nhung cong) or (dang cong)) tan hai cau*.
