• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky sang) OR (ky dang)) ma hoi. hieu ve cam duc va ((thanh lap) OR (thanh hai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky sang) OR (ky dang)) ma hoi. hieu ve cam duc va ((thanh lap) or (thanh hai)) cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ky sang) OR (ky dang)) ma hoi. hieu ve cam duc va ((thanh lap) or (thanh hai)) cua te*.
