The repository administrator, John, notices that the discovery facets are out of date, due to some changes to the configuration. Instead of rebuilding the discovery index from the command line interface, John clicks the "Discovery" link in the "Administrative" section of the side navigation. On the following page, a button is present which allows John to rebuild the discovery index of the repository. The dropdown list next to the button allows John to select if he wants to rebuild the discovery index for the entire repository, or for a specific community or collection.
