The document discusses search hubs, custom search engines, and automatically generated search engines. It defines search hubs as entities that act as a focus for collections of resources used as the basis for a bounded search. It also describes how custom search engines can now be automatically created and updated by placing code on a webpage, which will include in the search engine all sites linked from that page. This allows dynamic, tailored search experiences to be quickly generated without manually listing all URLs.
