chu xanh » chu manh, chieu xanh, chua xang
tranh va » tranh van, trang va, trinh va
va thong » va thuong, va phuong, he thong

• If you are trying to use Boolean operators, they must be ALL CAPS: cho chu xanh - canh tranh va thong duong manh ((toan cau) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: cho chu xanh - canh tranh va thong duong manh ((toan cau) or (toan tap))*.
