• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((((canh trinh) OR (canh tranh))) OR (hanh trinh)) van nhung cong dang thanh cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((((canh trinh) OR (canh tranh))) or (hanh trinh)) van nhung cong dang thanh cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((((canh trinh) OR (canh tranh))) or (hanh trinh)) van nhung cong dang thanh cao*.
