• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (hieu manh)) - thanh toan xuan ((nang cong) OR (dang cong)) van thanh hai.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (hieu manh)) - thanh toan xuan ((nang cong) or (dang cong)) van thanh hai".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (hieu manh)) - thanh toan xuan ((nang cong) or (dang cong)) van thanh hai*.
