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