• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - anh dinh va thong ((thong van) OR (thong quan)) ((toan cau) OR (van cau))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - anh dinh va thong ((thong van) or (thong quan)) ((toan cau) or (van cau))*.
