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