When a Google user does certain search queries, they’ll sometimes get a Knowledge Graph panel to appear, giving them the information they’re looking for. Google has added a new feature to the Knowledge Graph panel that allows users to share the search results on Facebook, Twitter, Google+, through email or with a short link.
The share icon is located on the left of the logo in the right-side knowledge panel.
If you click on it, share box will open, giving you the option to share the search page on Facebook, Twitter, Google+, through email or with a short link.
