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