US Patent 10089674 Ordering a set of data associated with an item

Techniques for ordering data associated with an item may be provided. For example, a first set of the data may be ordered based on predefined values of a first attribute. Based on receiving a request to further order the first set based on a second attribute, a second set of the data may be selected based on the first set and on a sizing window. The sizing window may be configured to define a size of the second set. Values corresponding to the data in the second set may be computed. These computed values may be used to order the second set of data.
