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