• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (hieu manh))) or (chieu sang)) - hanh tinh cua thong cong san ban can~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (hieu manh))) or (chieu sang)) - hanh tinh cua thong cong san ban can*.
