Looking for a plugin – Search team members within site with categories

Hi guys,

This is my second issue. I’m looking for a widget or plugin that search specific pages. I’m building a lawer website, and this site will have like 50 lawyers. So i wanted to have a search widget/plugin to find them. The idea is to search with categories (like pratice areas, keywords, names).

I found an example of what i’m looking for: http://www.servulo.com/pt/ – here you can see the search widget they are using. you can look people by Pratice Area; Name of the lawyer or Keywords.. Can anyone suggest me one? with a normal design.

I’m doing a page for each team member, so the idea is to seach specific pages!

Thanks in advance
