• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((thieu xanh) OR (hieu manh))) OR (thien anh)) - hanh trang cua thong cong san than tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((thieu xanh) OR (hieu manh))) or (thien anh)) - hanh trang cua thong cong san than tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((thieu xanh) OR (hieu manh))) or (thien anh)) - hanh trang cua thong cong san than tap*.
