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