• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (dieu hanh)) - thanh trung tam nhung dang thanh ((hoa cau) OR (hoa cac))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (dieu hanh)) - thanh trung tam nhung dang thanh ((hoa cau) OR (hoa cac))*.
