• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (((hieu lang) OR (nhieu tang)))) - manh tran tuan hang cong san toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (((hieu lang) OR (nhieu tang)))) - manh tran tuan hang cong san toan cau*.
