Google's Custom Search turned three in 2009, and it had arguably its biggest year to date. The technology is powering "many tens of millions" of queries a day on millions of sites, according to the company.

As many others are doing, Google is reminiscing about the year that is almost over, and reflecting upon some of its accomplishments. The Custom Search Team specifically is reflecting on some of its highlights for 3009.

Google lists the following as key developments for the year in custom search:

• integration with several hosters to bring Custom Search to your doorstep
• enabled support for rich snippets, giving you more control over presentation of results
• it's now easier for you to promote specific content to the top of your search results
• we deployed contextual search within Blogger, Google Sites and Wikipedia
• automatic transliteration is now integrated into the search box
• improved results rendering flexibility with the Custom Search Element
• plug-n-play with themes for enhanced customizability of results look and feel
• added support for structured metadata and the ability to restrict results by specific attributes
• we got you ready for the growing population of users searching your websites with mobile devices, such as Android phones, iPhone, iPod Touch, Palm Pre, etc.

Google promises additional metadata support in the new year, with more results customization and other features for Custom Search. With that in mind, it may be a good time to give Google you feedback, if you are a user of Custom Search. They're openly requesting it.
