hanh tang » hanh trang, anh tang, hanh mang
hang nong » thang long
manh toan » thanh toan, anh tuan, tinh toan
doi chau » doi chieu, gioi chau, hoi chu

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chau tinh - hanh tang cua ((hang nong) OR (han tong)) manh toan cau~.
• Adding a wildcard symbol may retrieve word variants: doi chau tinh - hanh tang cua ((hang nong) or (han tong)) manh toan cau*.
