Spotlight allows you to search for files by name or content. For example, to find a file named Customers, you could type Customers or just Cust into the search field.
If you don’t know the name of the file that you want, just type a word that appears in that file. For example, to find a file that contains a report about Microsoft, tell Spotlight to search for the word Microsoft.
You can access Spotlight through the Finder window or the menu bar. Using Spotlight in the Finder window searches only for files, while Spotlight on the menu bar searches for more than just files, such as contacts and web pages.
