Tip 1 of 12: New in El Capitan: new search technology

Apple's upcoming OS X 10.11 El Capitan software update introduces a new version of Spotlight (the search technology inside OS X).
The new Spotlight search system introduces "natural language" searching. This aims to make it much easier to find items on your Mac. So you'll be able to type things like "emails from Kate" or "photos from last June". Because Spotlight is integrated throughout OS X you can also use these search terms inside other apps, like Photos and Mail. You can even type complex phrases like "emails from Bob last year that contain documents" or "that presentation that I was working on yesterday".
