Search module modification

I need help modifying my search module(s). I have SOBI2 advanced, joomla basic, and pixpro. I dont think I need all of these. What I would like to see on my site is one basic search box, and then another with three specific search categories. Search by name, area, vocation. Is this something that I can do? I have seen it on other sites. I dont know if this is an issue where you can modify a file or if there is a specific module that I need to get in order to achieve this. My whole site will be based on ease of access/search ability of these three categories. Any suggestions would be greatly appreciated. I posted a note on newsline two days ago..still waiting for response...not sure if that was the right area to post my [hide]question.http://www.google.com/search?sourcei...tntjobz.net%2F[/hide]
Thank you.
