What setting is used to change the number of items displayed per page in search results?

The setting that is used to change the number of items displayed per page in search results is found in the "Items Per Page settings." This is a specific configuration option that allows users to control how many items they see on each page when conducting searches within the application. By adjusting this setting, users can enhance their browsing experience and improve the efficiency of navigating through search results.

The other options relate to different aspects of user interface settings, but they do not specifically address the control over item display counts in search results. Each option serves its own functionality, but for managing the quantity of displayed search items, the "Items Per Page settings" is the relevant choice.
