• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (nhieu tang)) - canh tranh vat thong cong dan ((than cap) OR (thanh cac))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (nhieu tang)) - canh tranh vat thong cong dan ((than cap) OR (thanh cac))*.
