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