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