how to get search to search users, events and everything else?

Hi there, I am using the new template ja intranet from Joomlart and basically they have a search module in the header of their site. I would love to use this as my global search tool like you would find on say twitter or facebook. Right now its just the standard search from joomla and therefore it does not search the users, events, or discussions like the toolbar search in easysocial would do.

I do not want to show 2 search bars and therefore I have hidden the toolbar for easysocial as it already exists of course in the top header of the site as you can see. So is there any plugins or anything that I can do to get the search on my site being able to search users and events and discussions etc? A type of global search. I provide all details below for you to help. Thanks for your time.
