• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((thiet tach) OR (thien hach)) - thanh trung cua hang cong ((xuan toan) OR (dan than)) ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((thiet tach) OR (thien hach)) - thanh trung cua hang cong ((xuan toan) or (dan than)) ban".
• Adding a wildcard symbol may retrieve word variants: ho ((thiet tach) OR (thien hach)) - thanh trung cua hang cong ((xuan toan) or (dan than)) ban*.
