• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi xanh) OR (chi anh)) - canh tinh cuong dung cong va ((van cau) OR (van hau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) or (chi anh)) - canh tinh cuong dung cong va ((van cau) OR (van hau))".
• Adding a wildcard symbol may retrieve word variants: doi ((chi xanh) or (chi anh)) - canh tinh cuong dung cong va ((van cau) OR (van hau))*.
