• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu manh) OR (hieu manh)) - thanh trung cap ((nhung cong) OR (hang cong)) ban than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu manh) or (hieu manh)) - thanh trung cap ((nhung cong) OR (hang cong)) ban than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu manh) or (hieu manh)) - thanh trung cap ((nhung cong) OR (hang cong)) ban than cau*.
