• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh tinh cua ban ((((nong thanh) OR (rong thanh))) OR (dong thanh)) san cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh tinh cua ban ((((nong thanh) OR (rong thanh))) or (dong thanh)) san cau*".
