15. Search Hubs Entities that act as a focus for concentrations of, or collections of, resources and/or pointers to resources that can then be used as the basis of a bounded search. Search hubs often occur naturally around particular topics or areas of expertise. Search hubs may be defined by entities that include resources, locations, people, dates and events.

25. Custom Search on the fly 6/12/2007 12:31:00 PM Posted by: Rajat Mukherjee, Product Manager Starting today, there's a new feature that makes Custom Search Engines (CSEs) even easier to create and keep up to date. You can now create a CSE by simply placing a small piece of tailored code on a page on your site. With that one piece of code, Google's search technology will automatically include in your new CSE all of the sites you have linked to from that page, creating a dynamic, powerful and tailored search experience really quickly. Moreover, your new CSE will update itself periodically to include any new links added to that page. So, if you have a blog or a directory-like site and don't feel like listing all of the URLs you want to search across, you can leave the work to us. With this new feature we'll automatically generate and update your CSE for you.
