Search is always available on the page. The Social theme has a static header that keeps the search field visible wherever a user scrolls on a page. Search automatically returns results for the context where it's being used. For example, while searching in a specific group, the header will say "Search in <group name>". If searching in a group's application, it will say "Search in <group name> 's <application>." Other filters or parameters can be applied.
Search quality is improved by using filter buttons that allow you to drill down to find what you are looking for within Content, Groups, or People. Using the Advanced Search functionality allows a user to refine their search even further furnishing more parameters for relevancy, content type, location, author, or recency.
