thong cong » trong cong, tong cong, thong thong
doi chieu » doc hieu, doi chi, ho chieu
manh toan » thanh toan, anh tuan, tinh toan

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - anh ((thuong cua) OR (thong tu)) thong cong ((dan toan) OR (manh toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - anh ((thuong cua) or (thong tu)) thong cong ((dan toan) or (manh toan)) cau*.
