Change the form of presentation, of the results in search.

Greetings Forum. I wanted to know, how can I change with CSS3 or some plugin. The presentation format of the search results. So that you do not see such a large picture, and for example, leave in a two-column column, with a short description of the product. and a link that says Read more. I think it would be more beautiful and manageable. If the results came out smaller, by horizontal rows. or with two rows, vertical. Can you help me?. Something like the plugin, to improve the WordPress Blog.

I have placed a link, so you can see how the search result is by default. Very big and ugly. ??
