• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh trung phan thuong cong ban ((((hang cau) OR (nang cao))) OR (nhung cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh trung phan thuong cong ban ((((hang cau) OR (nang cao))) or (nhung cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh trung phan thuong cong ban ((((hang cau) OR (nang cao))) or (nhung cau))*.
