nhu phuong » thu phuong, nhung phuong, thi phuong
trang cua » tranh cua, tang cua, trung cua

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trang cua ((nhu phuong) OR (bang phuong)) dinh toan cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trang cua ((nhu phuong) or (bang phuong)) dinh toan cau*.
