Result Plugins
Result plugins allow you to customize the look and feel of searches done in SearchMagic. You can learn how to download plugins in Downloading Plugins.
Select different plugins by going to the preferences (⌘+,) and clicking on the Appearance pane. Now, just select the one you would like and SearchMagic will show you a preview of how it will look. SearchMagic comes with a few plugins to get you started, but there are many more available. Once you have selected a plugin, type in a search and you should see results from that website.
