• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - hanh trung tuan ((nhung cong) OR (thong cong)) ((dan than) OR (dan chan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - hanh trung tuan ((nhung cong) or (thong cong)) ((dan than) OR (dan chan)) cau*".
