• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (hoc hien)) xanh - ((hanh mang) OR (hanh trang)) quy dung trong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) or (hoc hien)) xanh - ((hanh mang) OR (hanh trang)) quy dung trong dan than cau".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (hoc hien)) xanh - ((hanh mang) OR (hanh trang)) quy dung trong dan than cau*.
