Official Google Blog: “We’re transforming Google into a search engine that understands not only content, but also people and relationships. We began this transformation with Social Search, and today we’re taking another big step in this direction by introducing three new features:

• 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;
• 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,
• 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.
• We’re also introducing a prominent new toggle on the upper right of the results page where you can see what your search results look like without personal content. With a single click, you can see an unpersonalized view of search results.”
