• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (((chieu sang) OR (chieu xanh)))) - thanh tung tuan dang cong van toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (((chieu sang) OR (chieu xanh)))) - thanh tung tuan dang cong van toan cau*.
