• If you are trying to use Boolean operators, they must be ALL CAPS: cao hieu xanh - hanh tinh ((cua thong) OR (cua thuong)) hong anh ((tuan cau) OR (van thu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cao hieu xanh - hanh tinh ((cua thong) OR (cua thuong)) hong anh ((tuan cau) or (van thu))~".
• Adding a wildcard symbol may retrieve word variants: cao hieu xanh - hanh tinh ((cua thong) OR (cua thuong)) hong anh ((tuan cau) or (van thu))*.
