The Search Tab allows you to navigate a hierarchical list of the worlds available in the universe. You may also search for a world by name or keyword. World owners can set search keywords for their worlds in the world features dialog.

The search tab is actually just a web page. Whether or not it is available depends on the universe you are currently in. Some universe owners may have a different search page, or no search tab at all. Universe owners can specify the URL for the universe search tab from the universe attributes dialog.
