• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((thieu xanh) OR (hieu manh))) OR (thien danh)) - thanh thong qua trinh dung van than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((thieu xanh) OR (hieu manh))) or (thien danh)) - thanh thong qua trinh dung van than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((((thieu xanh) OR (hieu manh))) or (thien danh)) - thanh thong qua trinh dung van than cau*.
