Building on the improvements made to Spotlight in OS X 10.10 Yosemite, Spotlight in El Capitan offers a couple of notable improvements, including the ability to move the results window around on the screen and pull live information from the web and preview that information. Whether you're searching a local drive or the internet, Spotlight is a powerful but simple way to find what you need quickly. Though not new in El Capitan, it's worth noting that you can even use the search field as a calculator for simple mathematical operations (i.e. no support for variables or advanced functions). Just type in the math and Spotlight will automatically generate a result.
