Granularity of use. Should sort / search?

Question

How to determine what should I add to my usage diagrams? 1 for each button / shape? Should things like sorting and searching be included? Or are they, for example, under "list items"? Although the list of elements seems clear?

Answer 1

Use Case diagram is designed to identify important high-level business tasks, and not a list of system functions. For example, a system used to serve customers may include the research task of finding information to help someone in a support call.
