Today, Google added three new elements to its search capability – the concept is called Search Plus Your World. The three elements are (taken from the official Google blog):

  1. Personal Results, which enable you to find information just for you, such as Google+ photos and posts—both your own and those shared specifically with you, that only you will be able to see on your results page;
  2. Profiles in Search, both in autocomplete and results, which enable you to immediately find people you’re close to or might be interested in following; and,
  3. People and Pages, which help you find people profiles and Google+ pages related to a specific topic or area of interest, and enable you to follow them with just a few clicks. Because behind most every query is a community.

It hasn’t been fully rolled out but when you start to see it you will be able to find more content based on Google Plus shared content and profiles.
