• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh trang va thong cong tan ((((than cao) OR (toan cao))) OR (thoai cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trang va thong cong tan ((((than cao) OR (toan cao))) or (thoai cac))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trang va thong cong tan ((((than cao) OR (toan cao))) or (thoai cac))*.
