• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu sach)) - thanh tran tuan nhung cong ((van toan) OR (van thanh)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sach)) - thanh tran tuan nhung cong ((van toan) OR (van thanh)) tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu sach)) - thanh tran tuan nhung cong ((van toan) OR (van thanh)) tap*.
