How can I change the behavior of the Search module?

Hi Team,

I would like to accomplish below items for my search module:
- Disable / enable Advance search
- limit search to specific items, and have flexibility to include/ exclude also Album's name, Photo's name, or maybe even Group's name
- Actually I would like to limit the search AJAX search to only user's real name, Group's name, Event's name (in future) only.
- I cannot search user via the AJAX search but only advance search, is it the case?

Is it possible to do with 1.2.8 or I need to wait for some future release?

Please advise and thanks

Best regards,
Alfred
