Updated spotlight tracks location and usage data by default

From Mac Help

"When you use Spotlight, your search queries, the Spotlight Suggestions you select, and related usage data will be sent to Apple. Search results found on your Mac will not be sent. If you have Location Services on your Mac turned on, when you make a search query to Spotlight the location of your Mac at that time will be sent to Apple. Searches for common words and phrases will be forwarded from Apple to Microsoft’s Bing search engine. These searches are not stored by Microsoft. Location, search queries, and usage information sent to Apple will be used by Apple only to make Spotlight Suggestions more relevant and to improve other Apple products and services."
