cong thanh » dong thanh, cong trinh, cong tan
thanh pham » thanh phan, thanh pho, thanh hai
chi xanh » chi anh, chi danh, chi hanh

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chi xanh - thanh trung ((cua tong) OR (cua thuong)) cong thanh pham cau~.
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - thanh trung ((cua tong) or (cua thuong)) cong thanh pham cau*.
