• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh trung tuan ((thong cong) OR (tong cong)) ((gian nhung) OR (gioi nhung)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh trung tuan ((thong cong) OR (tong cong)) ((gian nhung) or (gioi nhung)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh trung tuan ((thong cong) OR (tong cong)) ((gian nhung) or (gioi nhung)) cau*.
