doi chieu » doc hieu, doi chi, ho chieu
trung cua » truong cua, trung tuan, trung cap
hang cua » mang cua, hang ca, huong cua

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - hanh ((hang cua) OR (trung cua)) nhung cong san ((toan cau) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - hanh ((hang cua) or (trung cua)) nhung cong san ((toan cau) or (toan tap))*.
