Abstract
A user device for storing or displaying content recommendations includes a search session manager receiving metadata associated with content. The metadata includes a received hierarchical identifier including a primary level and a secondary level unique to the primary level. A memory stores selected hierarchical identifiers. A search module compares the received hierarchical identifiers with the selected hierarchical identifiers. A screen display displays content from at least one of the primary level and secondary level based on comparing.
