You can use the LinkedIn Search bar to look for people with similar interests, role models, and Top Voices to broaden your professional network and expertise.
When you conduct a people search you can refine your search results by 1st, 2nd, and 3rd+ degree connections by using the Connections filter at the top of your search page. The search results will display based on what filter you've selected. Keep in mind that filtering your search by 3rd+ degree connections will include everyone that falls in your search criteria.
