hanh tranh » canh tranh, hanh trinh, hanh trang
cua nhan » ca nhan, cua ngan, cua nha
tong tan » trong tan, cong tan, tong tap

• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - hanh tranh ((cua han) OR (cua nhan)) tong tan toan cao~.
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sach)) - hanh tranh ((cua han) or (cua nhan)) tong tan toan cao*.
