• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc thieu)) sach - hanh trinh cua thong ((thong dien) OR (thong viet)) van ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (hoc thieu)) sach - hanh trinh cua thong ((thong dien) OR (thong viet)) van ban*.
