• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((thanh truong) OR (thanh tung)) cao tuong ((duong dang) OR (dung dung)) than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh truong) OR (thanh tung)) cao tuong ((duong dang) or (dung dung)) than cau".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((thanh truong) OR (thanh tung)) cao tuong ((duong dang) or (dung dung)) than cau*.
