How to View Your LinkedIn Connections
Use the search box and drop-down arrow next to the Filter By link in the middle of the screen to filter your list of connections.
Enter any keyword into the search box or use one of the predefined filters (Tags, Companies, Locations, Industries, and Recent Activity) to display connections who, say, live in a greater metropolitan area of a certain city or work in a particular industry. You can also click the Advanced link at the top of the page to bring up all the filtering options.
The drop-down lists contain options only for your first-degree connections.
After clicking the Advanced link at the top of the page, you simply expand the Industry filter by clicking the triangle next to Industry and then clicking Internet. LinkedIn can show you who in your network matches that request! If you're looking for an option in any of these filter lists that doesn't appear on the filter list, none of your first-degree connections have that option defined in their profiles.
