Google is celebrating the third birthday of Custom Search with many updates. Here they are:
Custom Search Themes – Now you can customize the look of Custom Search on your site with themes, which can be tweaked for color, font, background and feature adjustments.
Custom Search Skin on Wikipedia – On the flip side, you can contextualize your Wikipedia experience with a Custom Search skin. When enabled, the Custom Search skin provides Google contextualized search throughout Wikipedia. Learn more about the Custom Search skin for Wikipedia here.
Structured Custom Search – Going back to Custom Search for your site, there are three new structured custom search updates. You can add Thumbnails and Actions to the Custom Search Elements, which allows metadata markups. You can also now restrict search results using metadata attributes. And there’s a new Rich Snippets Preview tool.
