Search Social, Blog and Discuss

Hi

I have been trying to achieve search functionality that searches my entire site - Articles, Easyblog, Easydiscuss and Easysocial. So far, all I have been able to achieve is searching sections.

I do have the various search plugins for Easy blog and easy discuss installed and I have indexed the Smart Search component.

Also, I have tried installing and using the following modules:

Smartsearch
Search
RokAjax Search
Easy Social Search


So far, none have achieved a search of the entire site.

Is there something else I should be doing?

Any advice is most welcome.

Thanks

Steve
