• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu tinh) OR (lieu tinh)) - ((thanh tran) or (thanh thang)) tuan bang dong bang thanh cau~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu tinh) OR (lieu tinh)) - ((thanh tran) or (thanh thang)) tuan bang dong bang thanh cau*.
