• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu lang) OR (nhieu tang)) - thanh truong ((va dung) OR (va duong)) cong thanh tran tuan.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu lang) OR (nhieu tang)) - thanh truong ((va dung) or (va duong)) cong thanh tran tuan".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) OR (nhieu tang)) - thanh truong ((va dung) or (va duong)) cong thanh tran tuan*.
