How can Linda limit certain Spotlight searches on her Mac?

To limit certain Spotlight searches on her Mac, Linda can deselect Spotlight Suggestions in the Spotlight pane of System Preferences. This option allows her to customize what Spotlight includes in its search results. By disabling Spotlight Suggestions, she can prevent specific results from appearing, such as web search suggestions or recommendations that may not be relevant to her needs.

This customization is part of Spotlight's settings, which provide users with the flexibility to tailor their search experience according to their preferences. By fine-tuning what Spotlight searches through, Linda can enhance her productivity and ensure that search results are more aligned with what she wants to find.

The other options do not provide a viable means of limiting Spotlight's searches. Restarting her Mac and holding down keys does not influence Spotlight settings, adjusting parental controls relates to user restrictions rather than search functionalities, and uninstalling Spotlight is not a supported action since it is an integral part of the macOS system.
