Global Site Search: CSS styling of search results

I need to style the search results page, e.g.:

http://beta.nrocnetwork.org/site-search/?phrase=algebra

I need to hide the name and picture of the user who posted the item. That would be useful information for a blog, but we're using WP as a CMS. We just want the title and link.

There isn't a specific class/id for each element, just for the overall table. Can anyone help me accomplish this?
