• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (ho chieu)) sach - ((thanh thong) OR (thanh thuong)) cua dung duong quang khai cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) or (ho chieu)) sach - ((thanh thong) OR (thanh thuong)) cua dung duong quang khai cap~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (ho chieu)) sach - ((thanh thong) OR (thanh thuong)) cua dung duong quang khai cap*.
