• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (((chau tinh) OR (cuu tinh)))) - hanh dung cua nhung cong san toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (((chau tinh) OR (cuu tinh)))) - hanh dung cua nhung cong san toan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (((chau tinh) OR (cuu tinh)))) - hanh dung cua nhung cong san toan cau*.
