• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (chieu xanh)) - hanh tang cua dang song van ((quan cau) OR (toan cau))~.
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (chieu xanh)) - hanh tang cua dang song van ((quan cau) or (toan cau))*.
