A new custom object called parts has been created for Ursa Major Solar. Where should an administrator adjust how the object appears when it is found in the global search?

There isn't a dedicated 'Global search, parts, and global search Layouts' section in Salesforce setup for this configuration.

Page layouts control the display of fields and related lists on a record's detail and edit pages, not how the object appears in search results.

While 'search layouts' is correct, the path 'Global search, parts' is inaccurate; settings for an object's search appearance are managed within the individual object's configuration in Object Manager.

Administrators can adjust how a custom object, such as 'Parts', appears in global search results by navigating to the Object Manager, selecting the custom object, and then configuring its 'Search Layouts'. Search layouts specifically define which fields are visible in search results, lookup dialogs, and various list views.
