• The system first determines the results and then displays the matching titles along with their corresponding topical descriptions

• The system displays title detail along with the items and the available action on each item 

Alternative flows 

• No matches - The system displays message indicating no titles in the system match this criteria. 

Special requirements

Preconditions

Post-conditions
